It is more than difficult to find a good GPS review on the Internet. The reason is this: GPS devices all do the same thing. They show your location on an electronic map, and then show you how to get where you’re going. Now, by GPS device I mean a car GPS device that you buy separately from your automobile and either hang from a bracket on your windshield or put next to you on the seat.

So, the key to a good GPS review is understanding the features that various GPS devices offer at each price point.

What do all GPS devices have in common?

All car GPS devices that are on the market today have a touch screen where you can enter information into the unit, such as your destination address. All auto-calculate the route to that address, and all give you spoken directions of some sort as you drive to your destination. In addition to this, virtually all GPS devices come pre-loaded with maps, usually at least of the continental United States, have an internal battery for emergency use, and can toggle between 2D and 3D map views. (3D gives you a slightly more realistic view of what you should be seeing in front of you.)

There are exceptions to all of these rules, but almost all are in the older models.

Who are the industry leaders?

There are three main manufacturers of car GPS systems, Garmin, Magellan, and Tom Tom.

Garmin sells about one out of two of all the car GPS systems sold in the world. They are known for making a quality product. Magellan was an early leader in GPS systems that can route you to more than one destination. They do not have nearly the market share that Garmin has. Tom Tom is a late arrival who is quickly catching up. According to Tom Tom, their GPS system, the Tom Tom One, is the best selling system in the world.

What are the main features to look for in a GPS system?

In this GPS review, let’s start at the cheap end and work our way up.

You can buy a GPS system for less than $200. The Garmin nuvi 200 and the Tom Tom One, 3rd Edition currently sell for less than $200 at Amazon.

As you increase price, the main features you can add are

Voice prompts that actually say the street name

Cheaper GPS devices only tell you where to turn. They say something like, “Turn right, here.” A good feature to be aware of is having the GPS device actually say the street name of the road you need to turn on. So, instead of “Turn right, here,” a better GPS system would say, “Turn right on Highland Avenue,” or “Take a left onto the entrance to I-95.” Devices with spoken street names usually start around $300.

Another feature to look out for is real-time traffic and weather capability

Wouldn’t it be nice if your GPS device could not only tell you how to drive from Atlanta, Georgia to Charlotte, North Carolina, but could alert you to bad traffic conditions in time to take a detour? Well, many of the more expensive units can. How does your GPS device know what the traffic is like up ahead? GPS devices that have this capability are tuned to either an FM or satellite radio frequency that broadcasts this information. If your device has this function, then it will usually come with a free trial subscription to this service. After that, it’s going to cost you, but the cost is fairly low, especially considering how useful real-time traffic is. Along with real-time traffic usually comes real-time weather — an added bonus.

Any of the Garmin nuvis from the nuvi 350 up have FM traffic capability. The nuvi 350 runs slightly less than $300 at Amazon. If you want a Magellan that route you around hold ups, you’ll be paying $300 to $350. All of the Tom Tom’s have this capability, even the Tom Tom One, 3rd Edition, which is one of the cheapest units on the market, currently running around $200.

Do you regularly use your cell phone while driving?

I know I do. It’s problematic to hold the cell phone in one hand and negotiate your way through heavy traffic on a busy interchange. If your phone supports Bluetooth technology you can get a GPS receiver with that same capability and actually use it to make and receive calls. You answer an incoming call by just tapping on the touch screen. You make an outgoing call by either entering the number in your GPS’s touch screen key pad or by accessing numbers stored in the device — downloaded from your phone when you first set up your receiver. So, now instead of wearing that silly Bluetooth headset and looking like a member of the Borg Collective, you can just have your GPS device do double duty. If you make a lot of calls while driving, this is definitely a feature you need to think about.

As to what Bluetooth is going to run you, the Garmin nuvi 360 is their lowest priced Bluetooth model. It currently sells for slightly more than $300. Virtually all of their upper end products have Bluetooth. Two of the Magellan Maestro series, the 3250 and the widescreen version, the 4250 have Bluetooth. They run around $280 and $350 respectively. The Tom Tom GO series has Bluetooth. They run anywhere from $350 to $900.

Multi-destination routing

It’s not something that I use much, but it’s definitely worth knowing about. Multi-destination routing means you can enter multiple routes into your GPS at one time and it will calculate the best route that includes all of your destinations.

Garmin’s nuvi 700 series does this, as well as a couple of their StreetPilot series. Most of the Magellan Maestro series does this – they can be programmed to hold up to 20 separate destinations. As for Tom Tom, the GO 510 can hold up to 15 routes. As to price, the nuvi 700s run anywhere from mid-$400s to almost $700. The Magellans are slightly less expensive, running from mid-$200s to the mid-$300s. The GO 510 costs slightly less than $500 at Amazon right now. The voice prompts, Bluetooth, and multi-destination routing are three of the more important features to consider.

Also, you want to keep in mind what maps your device comes with. And, almost as important, how many preprogrammed Points of Interest are included in its database.

Points of Interest

(POIs) are names, addresses, and phone numbers of possible destinations, anything from the nearest Starbucks to Yellowstone National Park. The lower priced units come with less than 1 million POIs. That’s not enough, if you’re going to be using this feature. For use outside of your normal travel routes, you really want a few million POIs. Virtually all GPS devices now come with this, except the lowest prices models, like the Garmin nuvi 200, which only has regional maps and less than 1 million POIs. (There’s nothing wrong with fewer POIs, if you’re not planning on needing them, but they sure can come in handy.)

Yet another feature to keep in mind is screen size. The standard size is 3.5 inches. This is measured on a diagonal. So the screen for the nuvi 270, for instance, measures 2.8″ by 2.1″. The so called widescreens measure 4.3 inches on the diagonal. You’re actually getting 70% more screen this way.

Why is screen size important?

It has to do with ease and safety of use while driving. Personally, I like a wide screen, but then again, my car is fairly big and has a big windshield. The difference in price between a regular screen and a widescreen is about $80. That might be money well spent. On the other hand, if you drive a smaller vehicle with less windshield area, the wider screen might be more of a hazard than a safety feature.

Currently at Amazon, Garmin nuvis (their newer product line) run from $179 for the nuvi 200 to $699 for the nuvi 770. The Magellan Maestros are running from $168 for the 3100 to $356 for the widescreen 4250. Tom Tom’s GPS systems are currently priced from slightly less than $200 for the Tom Tom One, 3rd Edition, to $899 for the GO 700 (which is overpriced).

Whatever you do, don’t procrastinate. Even with a good GPS review, with all of these confusing choices it’s tempting to just wait for whatever the next model is going to be. What you’re missing by doing that is lots less stress while driving! Imagine, if you’re a guy being able to always (really) know where you’re going despite what your wife or girlfriend says. And, even better, if you’re a woman you won’t have to pester your husband or boyfriend to stop at the local gas station and admit that they’re lost – not an easy admission for a guy. (I should know!)

When you hear about General Positioning System (GPS) system, you should first consider the GPS receiver. It is the part of the device responsible of processing the signal sent by the satellite in the space to find out your actual location. The receiver is usually placed on the dashboard of your car or underneath it. It renders on a dedicated output device your screen your destination.

The entire GPS is a constellation of about 27 satellites rolling around the center of the Earth at a steady speed. Amongst these satellites, 24 of them are responsible of processing signals emitted by the receiver and the remaining satellites are used for storage purposes on case of an unplanned event. The GPS receiver is responsible of hooking up with satellites used for storage purposes and working out its position from that satellite by computing their distance. The mathematical tenet used for this purpose is named trilateration.

Trilateration can be achieved in two dimensions and also in three dimensions. The rationale of this mathematical principle is to work out a triangle where you are located at the center of it. As soon as the GPS receiver emits its position and makes a connection with other satellites, it immediately works out three nearest points and computes your position.

Three types of GPS receivers can be noticed: those which can be installed in a car, lightweight and mobile GPS receivers and tracking GPS receivers. It is obvious that portable receivers are a huge boon for outdoor activities.

Finally, it is good to know that the actual process of GPS receivers is a little bit more intricate than what was described in previous sections. However, throughout this article, although the main objective was to give a broad overview how they work in theory the next paragraph will delve into advanced details about GPS computations.

From previous sections, we learnt that the GPS receiver computes its distance to the nearest available satellites in space by noticing the time spent by the emission of a given signal from the receiver to the satellite. There are another category of GPS receivers that you have not mentioned throughout this article. In order to overcome the lack of precision of the traditional GPS receiver, differential GPS receivers were born. Their rationale is to estimate the level of GPS errors at a stationary receiver station with a location that was already computed before. Since the Differential GPS hardware at the station is already aware of its own location, it can work out its receiver’s level of errors in a straightforward way. The station then broadcasts a radio signal to all Differential GPS-equipped receivers in the nearby area, providing signal correction information for that area. In general, accessing this correction information makes Differential GPS receivers much more correct and precise than traditional GPS receivers.

The most essential function of a GPS receiver is to pick up the transmissions of at least four available satellites and combine the information in those transmissions with information in an electronic almanac, all in order to figure out the receiver’s position on Earth.

The basic principle of GPS navigation system to measure the known location of the satellite to the user the distance between the receiver and then integrated multi-satellite data can know the exact location of the receiver. To achieve this purpose, the satellite’s position can be based on-board clock time recorded in the satellite ephemeris identified. The user to the satellite’s distance from the satellite signal transmitted through the records to the user the experience of time, and then multiplied by the speed of light received (due to the interference of the atmosphere ionosphere, this distance is not the user and the real distance between the satellites, but pseudorange (PR): When the GPS satellites to work, it will continue to use 1 and 0 binary symbol composed of pseudo-random number (PN for short) launched navigation message. GPS pseudo-code system uses a total of two, namely civilian C / A code and the military of the P (Y) code. C / A code frequency 1.023MHz, repeat cycle of a millisecond, the code distance one microsecond, equivalent to 300m; P code frequency of 10.23MHz, repeat the cycle of 266.4 days, Code spacing of 0.1 microseconds, equivalent to 30m. The P code Y code is formed on the basis of confidentiality better performance. navigation message includes satellite ephemeris, work status, clock corrections, ionospheric delay correction, atmospheric refraction correction and other information. It is in the solution from the satellite signal modulation up to 50b / s modulation in the carrier frequency on the launch. navigation data included in each of the main frame 5 sub-frames per frame size 6s. the first three frames of all 10 code; repeat every 30 seconds, updated hourly. After the two were 15000b. navigation message in the contents of the main remote codes, code conversion, the first data blocks 1,2,3, including the most important was ephemeris data. When the user receives the navigation data, the extraction of the satellite time and do it with their own clock compared satellite and the user will be aware of the distance, and then use the navigation data in the satellite ephemeris data, calculate the location of the satellite launch when the message the user in WGS-84 geodetic coordinate system position, velocity and other information can be learned.
GPS satellite navigation system can be seen part of the role is to constantly launch navigation message. However, users accept the machine using the onboard clock with the clock can not always synchronized, so in addition to the user’s three-dimensional coordinates x, y, z, but also introduce a Δt is the time between the satellite and receiver differential as unknown, then four equations out of these four unknown solution. So if you want to know the location of the receiver, at least four satellites can receive the signal.
GPS receiver can receive the exact timing can be used to nanosecond time information; for forecasting the next few months in which broad locations satellite ephemeris; used to calculate the required positioning satellite coordinates of the broadcast ephemeris a precision of several meters to tens of meters (each satellite is different at any time change); and GPS system information, such as satellite status.
GPS receiver of the code can be measured from the satellite to the receiver, as with the receiver clock error of satellite and atmospheric propagation errors, it is called pseudorange. 0A code measured on the pseudo-range as UA code pseudorange, the accuracy is about 20 meters, measured on the P code pseudo-range as P code pseudo-range, precision is about 2 meters.
GPS receiver to receive satellite signals, decode or use other technology, the information on modulation in the carrier removed, you can restore the carrier. Strictly speaking, the carrier phase should be known as the carrier beat phase, which is received by the Doppler frequency shift effects of the satellite signal carrier phase and the receiver local oscillation signal phase difference. Generally determined by the receiver clock time measurement epoch, to keep track of the satellite signal, you can record changes in the value of the phase, but the start time of observation and satellite receiver initial phase of the oscillator is not known, since epoch beginning phase integer not know about that ambiguity, only as a parameter in the Data Processing Solution. Phase observations are accurate to the millimeter, but only solved ambiguity, only the relative positioning, and continuous observation for some time to use the phase observations, and to achieve better than the meter-level positioning accuracy of only phase observations can be used.
By positioning mode, GPS positioning into a single point positioning and relative positioning (differential positioning). Single point positioning is only one receiver according to the observation data to determine the way the receiver position, it can only use pseudorange measurements can be used for rough travel, etc. navigation. Relative positioning (differential position) is based on two or more receivers of observational data to determine the relative position between the observation points the way, both can be used pseudorange phase measurements can be applied, geodetic or engineering survey shall be phase observations using the relative positioning.
In the GPS observables includes satellite and receiver clock error, atmospheric propagation delay, multipath effects, etc. error, even when in the position calculation by the satellite broadcast ephemeris error, and during most of the public when the relative positioning error was offset or reduced, thus positioning accuracy will be greatly enhanced, dual-frequency receiver can view the two frequency ionospheric measurement error of the atmosphere to offset a major part in the high precision, when the distance between the receiver (there is significant difference between the atmosphere ) should be used in dual-frequency receiver.

Relativity for the GPS provides the necessary amendments
Global Positioning System GPS satellite timing signals to provide latitude, longitude and altitude information, accurate distance measurement requires precise clock. Therefore, we must use precise GPS receivers relativistic effect.
Accuracy within 30 meters in GPS receiver means that it has made use of the relativistic effect. University of Washington physicist Clifford M. Will explained in detail, said: “If you do not take into account relativistic effects, satellite clock on the Earth’s clock is not synchronized.” Relativity that fast moving objects with the passage of time slower than static. Will calculated for each GPS satellite approximately 1.4 million kilometers per hour across the distance, which means its on-board atomic clocks on Earth every day the clock slower than 7 microseconds.
The gravitational force exerted on time more relativistic effects. About 2 million meters of altitude, GPS satellites by the gravitational pull by approximately one quarter of the ground. The result is that on-board clock speed of 45 microseconds per day, GPS should be included in a total deviation of 38 microseconds. Ashby explained: “If there is no satellite frequency compensation of 11 km per day will increase the error.” (This effect is in fact more complex, because the satellite along an eccentric orbit, sometimes closer from Earth, sometimes Also very near.)

Marine GPS based devices are a boon to all seafarers. It is based on the Global Positioning System or GPS. It is a constellation of satellites which orbit the earth twice a day, transmitting exact time and position information. With GPS, you can spot your precise location and get back to your original destination. A marine GPS can be of a great help should you get lost in any large body of water – lakes, seas or oceans.

A marine GPS device’s use starts off the first step prior to going out to sea – voyage planning. One of the most vital advantages of using marine GPS is that it is a device commonly responsible for saving lives. In addition, marine GPS also reduces the chances of getting lost at sea.

Normally, marine GPS systems are used by the Coast Guard to keep track of ships as they move along the coastlines. This will give them an idea of the direction in which a vessel is heading. They may be able to communicate with the vessel and provide precise information regarding its current position and directions to take to get to its destination.

With marine GPS technology, planning routes for other ships have been made possible for the crew. In addition, this technology also helps in avoiding collisions that may cause fatality or other accidents that may cause damage to the ship.

Basically, there are many different kinds of marine GPS in the market. They range from voice-enabled computer systems to simple radar-oriented GPS systems. The more popular marine GPS systems will be the one that is voice-enabled. Somehow seafarers relate to this type of marine GPS systems since they find some comfort in listening to a ‘human’ voice; though it may be a computer generated one. As for the radar-oriented GPS systems, they only give off a beep as a form of signal. This makes the interaction with the marine GPS a less ‘personal’ one; although they are very effective in locating positions.

People usually perceive that they need lots of sea knowledge in order to operate a marine GPS. However this is not the case. Just like any other GPS system, all you need to do is to read the manual and understand the signals that are shown on the GPS device. Thereafter, you can program the marine GPS device according to the requirements of your journey on the high seas. Whether you use a marine GPS on land or at sea, they provide user friendly interfaces that makes them easy for everyone to operate.

It has been ages since the military has been using GPS to monitor the enemy and ascertain locations that are important for their operations. GPS vehicle tracking technology is crucial to operations where the military needs to scout and locate places that will not be found on any major mapping devices.

GPS tracking is critical to the military as it can identify the type of vehicles used by the enemy and get their exact location within seconds. With this level of timely and detailed information, the chances of completing an operation successfully are very high.

GPS tracking systems are very beneficial to police officers, too. One of the reasons is because police officers can use GPS tracking to keep tab of suspects and fugitives. They can keep track of the location of the vehicle they are pursuing without being discovered by the suspects. Also, with GPS vehicle tracking, police officers can get to the perpetrator’s location without engaging in a dangerous high-speed pursuit through crowded neighborhoods and along busy highways. A GPS tracking device is a great tool for police enforcement in the event of lost or missing vehicles and their potentially expensive cargo.

GPS based vehicle tracking is also useful for ordinary folks like you and I. It can be used for personal and commercial use. In our high-tech world, this system has become one of the best inventions that assist us with our daily tasks. Almost all drivers are grateful for their GPS vehicle tracking systems. With the GPS tracking system, fleet owners and managers are now able to track their vehicles effectively. This is the main idea and rationale behind the GPS vehicle tracking system. When fleet owners and managers need to locate their employees and vehicles urgently, they can rely on the GPS tracking system to get the job done.

GPS Vehicle Tracking Has Additional Purposes

Many people who use a GPS system as a form of anti-theft device. Should there be any unauthorized movement of the vehicle, some of these devices may have the capability to disable the vehicle’s engine. With a GPS system installed in the vehicle, car owners can have piece of mind.

There are people who use GPS tracking to keep track of some important people in their lives or of their vehicles when they are not in town. Usually, parents will use GPS tracking to keep tab of their teenage kids should they attempt to drive the family car. Although it may seem like prying, in some cases, the caution is warranted.

GPS vehicle tracking technology offers all owners of vehicles peace of mind. Although this comes at a cost, in most cases the vehicles or the cargo they carry or the people they transport are worth every single cent paid for this technology.

A Variety Of GPS Tracking Systems For Different Needs

There are many different kinds of GPS vehicle tracking systems. Some are more suited for personal use; others for business users. Some examples of GPS vehicle tracking system are:

1) Wireless GPS tracking system
