Communications GPS

GPS navigation systems use a small receiver inside your dashboard unit. This receiver picks up signals from a minimum of three satellites orbiting the earth; the triangulation method. Much like navigators used in the days before technology, your system "triangulates" your position based on the intersecting point of circles that represents the distance from each satellite in relation to where your unit is. Then usually a fourth satellite is used to determine movement and speed.

These systems can be used two ways, the first is as a locator. The GPS system emits a locator beacon for satellites to follow. Police departments use this in conjunction with a company called "Lojack". A tracking center monitor the movements of several people or vehicles in real time. Weather its to hunt down a criminal in a stolen car, the military tracking its troop movements or a mother in search of her lost child. GPS systems are here and affecting our everyday lives.

In order for navigation to help you to your destination it needs a map to guide itself and you. Most of these units include that in the package when purchased. Usually in the form of SD card (scan disk), more maps can be downloaded from the companies website. The systems don't always work by themselves, but often are used in conjunction with other technology. Traffic data suppliers collect data from road sensors, local dept. of transportation, listening to police scanners and even using transportation companies fleets of trucks to gather information. Road network data is received and distributed for two main informative streams. Incident data, that identifies and signals all GPS units in the vicinity to be aware of an accident or roadwork. Then there is flow data showing the average speed vehicles are currently traveling on a particular section of road.

Now that most GPS systems are affordable, they can be picked up pretty much anywhere. Most for under $200, they make great gifts and when combined with services such as traffic and weather,. They have become invaluable to daily commuters and trucking/taxi services. Even local and Federal governments use them in their vehicles. Making them easy to take for granted, affordability and multiple daily uses makes these items perfect for anyone and everyone.

What is an Automobile GPS System?
I am sure you don't need me to tell you what automobile GPS systems are, but if you are reading this and you are not quite sure, then I will just tell you that they are electronic devices that know where you are.

Potential for Car Journeys
The clever thing is, that they know where you are in relation to other places. As soon as you know where you are, and where you want to go, then a whole raft of possible uses for automobile GPS systems suddenly becomes open to you for your car journeys.

Where Am I?
The main component of the system is a reliable method of determining your current position. This is based on satellite navigation and the device needs to get a 'fix' on your position from at least 4 different satellites out of the 31 (2008) in orbit above the Earth. This is so that it can effectively know where you are, both horizontally and vertically on the surface of the Earth. The electronics for this are fairly well established these days since the US military developed the GPS system for its own use. GPS navigation became officially available to the public in 1996 (wikipedia), and since then, the use of automotive GPS systems have blossomed. In the early days, the accuracy allowed by the US military was limited to a less-accurate version of the military's then current system. Now, however, accuracy has been improved and positions are often able to be determined within a 6 metre radius, depending on the receiving technology, the local terrain and a clear line-of-sight view to the satellites.

Where Are You?
A position for the automotive GPS system in your car is not much good without a map of the area, so that the device knows where it is in relation to other places. The map is probably the next most important part of the system. Any route from A to B must be reduced internally to a series of co-ordinate points describing all possible ways you might arrive at that destination. Each place where the road or highway changes direction or forks, must have an absolute co-ordinate associated with it. The smaller the distance between these points, the better and more accurate the map inside the unit will be. Knowing this, you can understand how a really good software map is essential, and why new updated maps are necessary to take into account new and improved features along all your potential journeys.

Show Me Where I Am.
Once the position in relation to other places is determined, the unit needs to be able to output the information in a way that is immediately understandable to the motorist. Traditionally this is done through a small flat screen as part of the unit's construction and sometimes also via text-to-speech spoken output through a loudspeaker.

Where I Want To Go.
An output that is clear, and easily understood is essential, but so too is an input, so that the start and destination of the journey may be entered into the automotive GPS system. The main ways this is done, is through a touch screen interface, using buttons and text boxes to describe your destination. However, major manufacturers have also developed speech recognition systems capable of being used as input to the unit, and now other smaller manufacturers are following suit. This is likely to become the primary input method in the future, as it allows the driver to operate the unit and still safely keep both his hands on the driving wheel.

Conclusion.
Now that I have described the main components of an automotive GPS system, you can understand how all the different makes and models available on the market have these four main core functions. Manufacturers add value and make models different, by building into their systems other inputs or outputs, extra features, better more accurate maps, quicker acquisition of satellite positional 'fixes', points of interest, etc. The solution to determining which automotive GPS system to buy, is nothing more than deciding which extra features you require for your driving needs. These needs can be found out by analysing how you are going to use the GPS system that you will buy, however, sometimes deciding which make and model is really best for you, can be the most difficult part of the buying process.

The use of GPS Fleet Management, also known as Vehicle Tracking or Vehicle Telematics, is increasingly common in today's business environment, both in the private and public sectors.

As the use of GPS Location technology has developed and become more widespread, so has the scope of its use widened. Once the domain of the Fleet Manager used as part of Vehicle Tracking system, GPS Location technology has now extended beyond the fleet department and into the hands, literally, of non-vehicle based staff.

Many organizations with a reliance on a vehicle based workforce have invested in GPS Vehicle Tracking technology to help administer a number of functions related to fleet and driver management, including: Vehicle journey time calculations, Vehicle mileage monitoring, Route planning, two way messaging, Driver behaviour analysis, Fuel usage reporting, Vehicle Service Scheduling and Job Schedule Adherence reporting.

Being able to monitor the real-time location of vehicles across a fleet, means organizations are now more able to respond dynamically to changing events and meet the increased expectations of their customers. Assigning the nearest available fleet asset, based on actual and accurate information produced by a vehicle tracking system improves response times and improves customer service levels.

The advent of person based GPS Tracking can complement existing Vehicle Tracking systems and ensure that non-vehicle based mobile personnel, such Street Cleaners, Park Rangers or Community Support Officers can now also be efficiently deployed, based on precise and accurate Location information.

Increasingly defined rules and guidelines pertaining to employers responsibilities under Health and Safety and Duty of Care legislation, means the benefits of this technology is increasingly being as much more than just a tool used to increase efficiency and productivity.

Advice published by both the HSE and Business link says that if you employ lone workers, you have the same responsibilities for their health and safety as for any other employees. You may, however, need to take extra precautions to ensure lone workers are at no greater risk than your other employees.

What is a Lone Worker? According to the same advice, a lone worker is anybody who works alone. The term itself makes is quite clear. The advice continues; A Lone Worker can include; self-employed people and employees who work away from their business base. This occurs in a wide range of business activities, such as transport, construction, maintenance and repair.

In addition to being a tool that provides a location and journey history, Lone Worker GPS Tracking devices, now also serve as personal security devices and include the ability to make and receive voice calls, send a Panic Alarm, which when pressed, transmits an Alarm message with the precise location of the device carrier. Many units also include a Motion Sensor which transmits an alert location if the carrier falls, is lying prone and perhaps requires emergency assistance.

Businesses and organizations, who may have initially introduced GPS Location technology such as vehicle tracking, primarily to maximize the efficient use of their fleet and drivers, are now finding that GPS Location and Tracking technology can also help them meet their other duties and responsibilities.

The Global Navigation System was designed for the US Military. The first GPS satellite was launched early in 1978 and the twenty fourth of the first generation satellites was launched in October 1985. The launching of the GPS system forever changed the way wars are waged and ultimately land and water navigation by the public around the world. President Ronald Reagan decreed the GPS signals were to be available to the public for their benefit. Receiving GPS signals is free if you own or purchase a GPS unit.

The only difference in the signals received by the US Military and the public is signal accuracy. Signals received by the public are accurate to within one meter anywhere in the world. Military GPS signals are more accurate. Also US government installations and other sensitive sites are automatically blocked from civilian GPS units for the sake of safety.

The GPS satellite system is managed by the US Air Force. These satellites orbit the earth in precise orbits once each day.

Civilian use of the GPS system has taken off in the last ten years. Units are now available for practically any use you can imagine. Units are available for cars, commercial trucks, agriculture, ships, boats and multiple other uses. Handheld units have become very popular for hunting, fishing, camping, hiking, biking and units are available that are only used to track people, cars and animals. Of course surveyors and map makers also use GPS technology. Ocean going shippers now use individual units in cargo shipments to keep up with cargo for more accurate timing and delivery operations. Carriers such as UPS use GPS units for more precise routing and finding addresses for delivery.

Other governments like Russia and China are working on GPS technology for their own use. It seems like the world has really taken notice of our Yankee ingenuity and is trying to catch up with our technology.

GPS receivers need data from three satellites for basic navigation and four for precise information. WAAS is a synonym for Wide Area Augmentation System, developed for the Federal Aviation Administration for aircraft safety. Using WAAS planes can take off and land without any visual information. It allows accuracy to within three meters anywhere in the world.

Join the GPS revolution and realize the benefits.

It's a fact; no one can participate in or even think about locating a cache, no matter its difficulty rating, without a reliable and accurate GPS unit.

Keep in mind, however, that not all GPS devices are the same, and the same features that would be absolutely necessary in order to be the best GPS for geocaching to one person, might be considered almost incidental to the next.

So, the best GPS unit for Geocaching for any individual is probably a personal matter depending upon their skill level, physical conditioning, terrain, and difficulty of the cache.

Geocaching is not only frenetically catching on, you might say, because of the ever increasing worldwide access to the Internet, it is sweeping the globe. Individuals, groups, and organizations are hiding caches and posting them for all to see online.

It's easy, just boot up your computer, and target a cache of your choice. It can be near your home, down at the local park, near a river bank, on the side of a mountain or smack in the middle of some desert. Literally, caches are placed all over the world.

People from all walks of life, from all countries, and from all economic levels are quickly becoming avid participants in the fun, exciting and challenging treasure hunting game of geocaching.

And, if you're just beginning the sport, there are a number of important GPS features that would be beneficial to and enhance your early success as a geocacher. Some of the more recent GPS units even have built-in features that are geospecific to the adventurous game of geocaching.

Here are critical GPS features to consider before purchasing the GPS device that you'll be using when tracking down a cache:

1. Look for a screen that is of decent size, with good contrast, and make sure that it is easy to read. Also, check to make sure that it has trans reflective properties for easy readability in bright sunlight.

2. The GPS should be able to lock onto satellite signals quickly, and it should be accurate to within ten feet. The device should provide guidance through heavy tree and cloud cover, or while in your pocket, or even through the windshield of your auto? For this, you may want it to be WAAS-enabled for accurate pinpointing of caches, and you'll need twelve parallel channels.

3. It should be fairly small and lightweight for easy carrying. Look for one that will be small enough to fit into your pocket.

4. It should be easy to understand the information you're receiving. You'll want your GPS unit to have the capability of marking no less than 500 waypoints. These are significant points along the way. This capability will help you find caches easily and will, most importantly, keep you from getting lost.

5. The unit you choose should be waterproof. At some point, on one or many of your hunts, your GPS will get wet. You may drop it in a puddle, it will come a torrential downpour, you'll slip in a river or stream, trust me, you can plan on its getting wet no matter how many plastic bags you bring along.

6. How sturdy and rugged is it? As a natural part of geocaching, your GPS will get dropped and roughed up a lot. If you're a hiking/camping geocacher, you may be receiving information that will take you through brush, over rocks, across rivers, and through forests. Naturally, your unit will get banged up.

7. Finally, the GPS you choose should have a descent battery life. Generally speaking, the longer the battery life, the better, but also, the bigger the battery, the heavier the weight of the GPS. If you weigh 110 lbs., the unit's weight will be a real consideration. If this is the case, you could opt for a lighter weight device, and just take along some extra batteries. In no event, do you want your GPS to quit on you before you locate the cache.

You can find GPS units with all of these features in almost every price range, size, shape and color, but you should make sure that the one you actually purchase for your geocaching treasure hunting adventures at least has these minimum features.

Ryan Westmoreland enjoys the adventurous game of geocaching, and runs a blog all about the best GPS for every geocaching style and skill level. He gives up-to-date GPS reviews, finds great GPS equipment at bargain basement prices, and his tips will help you to be successful at geocaching from your first target cache.

The Global Positioning System (GPS) means the GPS receiver. This useful system was developed by the US defense department which later became available to everyone else. It is such a useful device, that people would like to have it while traveling by road but it is certainly no magic so as to give you each and every location and map readymade. Most of Global Positioning System (GPS) navigation devices come with the built-in maps but lot of these maps are not with adequate information and details. In order to overcome this hindrance while you are driving or outside and depending on the maps, you will need to have maps designed by you which will give just the information that you require. These customized maps created with your GPS are reliable as they are carefully designed in accordance with your requirement. You can now map out your travels by using a free software and access to internet of course with the help of a personal computer.

Deciding on which new Garmin GPS to buy is a difficult task. There are many kinds of GPS so in this article we will concentrate on portable automotive GPS units and leave the other types for another time. Odds are you were looking for an portable automotive GPS anyway.

For most people, the cost of the GPS is the first consideration.

A new Garmin automotive GPS will cost in the low one hundred dollar to the low four hundred dollar range (USD). As you would expect, the less expensive GPS will lack the advanced features of the more expensive ones.

Another selection criterion to consider is whether or not the Garmin GPS has been discontinued. If you are looking for a new Garmin GPS, I am assuming that you do not want a discontinued unit. As of the writing of this article, Garmin lists 26 current automotive GPS.

Garmin's newest GPS are the Nuvi 1200, 1300, and 1400 GPS series (9 GPS units in these series). However, these GPS have not gained the popularity of the Garmin Nuvi x5 GPS. To identify the x5 Garmin GPS models, look for the last digit in the model number to be a five (5). Examples: Nuvi 255W, Nuvi 755T, Nuvi 765T, Nuvi 885T.

The lowest priced new Garmin GPS is the Nuvi 205. It currently sells for approximately $125. The highest priced unit is the Nuvi 1490T that sells for approximately $410. (Note: prices are quoted are from Amazon).

As a word of advice, purchase a GPS that speaks the street name on which you will turn. Otherwise, you must to take your eyes off the road to read the street name on the display. Taking your eyes off the road for just an instant is extremely dangerous. The Garmin Nuvi 255 is the lowest cost, newest Garmin GPS with this feature.

If you are overwhelmed by all these GPS numbers and models, you may need some additional help to determine which are new, which are discontinued, which are current, and the basic features of each unit. Consult the resource information at the end of this article for additional help.

John V. W. Howe is an entrepreneur, author, inventor, patent holder, husband, father, and grandfather. His degree in physics makes him curious about how things work and he was naturally fascinated with early GPS units and has followed their development.

Let me tell you straight up. I truly believe that Garmin GPS Systems are the best on the market. No other company provides the features and quality of product that Garmin does at their price points. However, There are so many Garmins on the market right now that it could be hard to figure out the best one for your needs. While all are good choices, each is separated from the other by their features, styling and upgrades. Choosing the right one for you basically comes down to the upgrades that you want. Upgrades might include more intensive map regions, bluetooth capabilities, speech recognition, and voice turn-by-turn directions. To me the progression in price is comparable to other electronics. The thinner, lighter, sleeker the product - the bigger the ticket that will come with it.

If you aren't sure where to begin, take a look at the Garmin Nuvi 700 series. While not the cheapest Garmin choice, the Nuvi 700 series should be looked not as an expensive portable navigation system, but as an entry level device comparable to high-end in-dash car navigation systems. All 700 series Nuvis are wide and sleek, have sunlight-readable displays, and options like route planning and an emergency locator. Additional features such as Bluetooth compatibility, mp3 player, pre-loaded street maps for Europe and North America, and local and custom points of interest ( POI ) are enhance this outstanding product. With MSN direct services, the Nuvi 700 series becomes a virtual travel helper, with the facility to update traffic, stories and weather in real time.

The biggest difference between the Nuvi 700 and 800 series models is that 800 series have advanced speech recognition capabilities. While 700 series gives you mostly hands-free control, the 800 series gives you complete hands-free use for you to navigate menus and use voice commands (which is really helpful in "hands-free" Washington, DC). While the 700 and 800 series gps systems are considered the "luxury" class in portable gps, the Garmin 5000 is definitely the working man's gps.

It has the biggest screen of all Garmin Nuvi products and is designed to be a dedicated car gps unit. These products are superb for in your RV or Wagon . Real tech heads can connect the gps with a camera to help with safely backing up a big automobile or wagon. They are particularly helpful for pro salespeople or pro drivers. The navigation features are the other reason this unit is valuable to the dedicated traveler. Nuvi 5000 incorporates Town Navigator NT street maps, 1,000,000 POI and up to three thousand programmable favorites. Some added extras include Garmin games, jpeg picture spectator, and mp3 player.

A global positioning system is very useful if you don't want to stop every time to ask for directions or if you don't want to consult a map on a trip.

GPS navigation systems for cars these days do more than just telling the fastest route from point A to point B. They can show you which route will take the less time, routes with less stops, toll booths which is another benefit because it will save the driver gas, which does cost a pretty penny these days.

Usually when one person buys a GPS system, there is no reason to buy a new one as it is something that doesn't need to be upgraded regularly.

Plus, the information provided doesn't cost the owner one cent, ie free. Although some models charge a small monthly fee to get optional information such as the weather.

GPS manufacturers like Tom Tom, Garmer and Nuvin want a piece of the pie in terms of market share, so they will often load their models with such features as the ability to sync it with your cell phone via Bluetooth or a voice that will tell you the name of the street.

Others will tell you if you exceed the speed limit, will connect your mp3 player to it or even view pictures.

For the driver who takes the same roads or simply drives locally, there's no need to buy a gps system. If you regularly take streets with big traffic, a gps can warn you ahead so you can take measures to avoid it.

If you want to buy one, be sure to check for sizes as many models can weigh close to a kilogram. Be sure to pick one with a big screen so you can enter data more easily.

Nowadays, gps systems come with a rechargeable battery, useful if you want to take with you for a walk. You can either charge with an electric plug or with a computer usb.

If you rent or travel often, buying one could be useful as most of them can fit in your pocket and can be easily installed on the dashboard. Your cellphone can act a navigation system too but you will have to pay a monthly fee, be sure to check your cell phone provider.

The ability to know where you are, where you want to go, and how to get there was once best found by using a paper map. If you were traveling in your car then there is a good chance you used either an atlas or one of those big tri-folded maps which really weren't much help while trying to drive. Thankfully navigating the world today is easier thanks to the Global Positioning System (GPS) and the different types of GPS devices that use it.

If you are wondering how these GPS devices do what they do then read on. The Global Positioning System was created and implemented by the United States Department of Defense when it launched its first GPS satellite back in 1978. Today there are 24 satellites in the GPS network that are the cornerstone of the whole system.

There are several different types of GPS devices that are designed to take advantage of this constellation of satellites. GPS mapping devices are used to collect points and any data attached to those points for mapping purposes. In fact these devices have been used for years to collect the data that creates the maps and mapping features used by other GPS navigating systems.

Which brings us to the most popular consumer GPS device; the GPS navigating system. The most familiar of these is the in-car GPS unit that shows you map of where you are going and tells you through voice commands how to get there. These GPS devices are either mounted in the cars dash or are portable and can be moved between vehicles. Some navigational units offer a feature whereby you can find restaurants, shopping, hospitals, and accommodations regardless of where you are; this can be incredibly useful when hunting services in a town with which you are unfamiliar.

The smaller versions of these navigational units are handheld devices that can be used by backpackers, hunters, and other outdoor enthusiasts. These types of GPS units will keep track of where you are, leave a breadcrumb trail of where you've been, and will guide you to where you want to go. Many of these units also feature built in cameras and voice recorders, letting you keep a record of your journeys.

The last device we'll discuss is a GPS tracking device. Much like in the movies these devices use the GPS satellite system to track objects to which they are attached. Many newer cars use these in the case they are stolen they can be quickly tracked and found. You can also find small GPS tracking units on certain cell phones, which can come in handy for the parents of teenagers.

There is a GPS device for just about any application and as the technology advances more features will come into being at lower prices.

There is no better choice then Magellan GPS Systems when it comes to finding your way in the world. To learn more about Magellan GPS Systems please Click Here.

Garmin voice recognition could save your life. Let's face it. GPS are a great help in navigating, but GPS are also very dangerous. Every time you start up your GPS, you have to agree to the disclaimer on the start up screen that says "Do not enter route information or adjust this device while driving. Failure to pay attention to the operation of your vehicle could result in death, serious injury, or property damage. You assume total risk and responsibility for using this device". You can be certain that this would not be displayed each time you start the GPS if Garmin were not concerned about your using the GPS incorrectly thus endangering your life and the lives of others.

The danger in using a GPS lies in your having to take your eyes off the road to poke your command or information into the touch screen on the GPS. Do you really pull over and stop to do this? If you do, you are the exception, since most people enter information into their GPS at 70 MPH.

Garmin created the solution to this problem with Garmin voice recognition in the Garmin Nuvi 800 series GPS. This series contained the Nuvi 850, and Nuvi 880. These units have subsequently been replaced by the Nuvi 855 and the Nuvi 885T.

You might think, "How does the GPS know when I am speaking a command and when am I talking to someone"? Good question. The Garmin GPS comes with a remote control button that mounts on your steering wheel to indicate to the GPS when to listen for your commands.

To use Garmin voice recognition, push the remote control button and speak the command. For example, say "Find Address". Then speak the address. The GPS will verify the address and then recalculate the route to it. You never take your eyes off the road.

Both the Nuvi 855 and the Nuvi 885T contain Garmin voice recognition and are identical in all features except the 885T additionally contains Bluetooth® and MSN® Direct with receiver and service subscription in the price. As you would expect, the Nuvi 885T is more expensive than the Nuvi 855.

When you purchase your next GPS, seriously consider paying the additional amount and purchase a unit with Garmin voice recognition. It will make your driving much safer.

For more information about Garmin voice recognition and the Nuvi 885T, consult the resource information at the end of this article.

You can use your GPS capable cell phone as a tracking device to locate lost children. GPS means Global Positioning System. Many cell phones are GPS capable through a wide variety of networks. You should ask your cell phone provider if your particular phone has this ability and if their network supports the technology. Most do, but please check on this.

Thee function must be turned on manually to use your phone's GPS to track a lost child. When I was at the phone store and asked could my phone track my child the sales man happily reported "yes". He did not, however, tell me that it could only do this if I was to go into my phone's settings, find the setting, and manually turn it on.

The setting must be set on "Location On" and not "911 Only" to use your cell phone's GPS device to track a lost child. Go to your phone's main menu, then to settings, then to "location", and you should find the option there. Note that unless you enable this option your location can only be tracked if you dial 911.

The battery must be in good condition and charged to use your cell phone's GPS device to track a lost child. The phone can be turned off and still be tracked, however, a phone with a dead battery will not send a signal.

The child must be carrying this phone on his/her person to use the cell phone GPS device to track your child. The phone is of no use to you or your child if they have a cell phone with no charge or they leave the phone at home. You might wish to get in the regular habit of checking your child before they leave the house to be certain they have their charged cell phone on their person. They need to carry the phone in a secure pocket or purse not easily lost or dropped.

If your child is not home by the time you expect them, or does not respond to your call, you should immediately, and with no hesitation, contact the police by dialing 911. Immediately give them your child's cell phone number and ask them to begin immediate tracking of the phone. Do not hesitate, precious minutes matter. If you have been mistaken and your child walks in the front door 30 seconds later you will hug and be oh so happy. Never wait if you think something is amiss. The police will be happy your child is home safe.
