Global Positioning Systems

GPS is a Satellite Navigation System -- an innovative breakthrough that has revolutionized travel and navigation of all kinds. This lens features the best GPS tools plus vital information about how GPS works so you can take advantage of this new technology!

Included here are both basic information of the science behind Global Positioning Systems technology as well as reviews and features of some of the best GPS devices available in a variety of areas of use.

The Global Positioning System (GPS) on Wikipedia 

gps satteliteThe Global Positioning System (GPS) is the only fully functional Global Navigation Satellite System (GNSS). Utilizing a constellation of at least 24 medium Earth orbit satellites that transmit precise microwave signals, the system enables a GPS receiver to determine its location, speed and direction.

Developed by the United States Department of Defense, it is officially named NAVSTAR GPS (Contrary to popular belief, NAVSTAR is not an acronym, but simply a name given by Mr. John Walsh, a key decision maker when it came to the budget for the GPS program[1]). The satellite constellation is managed by the United States Air Force 50th Space Wing. The cost of maintaining the system is approximately US$750 million per year,[2] including the replacement of aging satellites, and research and development. These costs are funded by the US and GPS is free for civilian use as a public good.

GPS has become a widely used aid to navigation worldwide, and a useful tool for map-making, land surveying, commerce, and scientific uses. GPS also provides a precise time reference used in many applications including scientific study of earthquakes, and synchronization of telecommunications networks.

Our Well Researched Top GPS Top Picks 

We spent a lot of time and testing so that you don't have to. Here are our picks for the best GPS technology currently on the market including a wide variety of different kinds of gadgets for differnet uses!

How GPS Works 

gps diagramWhen people talk about "a GPS," they usually mean a GPS receiver. The Global Positioning System (GPS) is actually a constellation of 27 Earth-orbiting satellites (24 in operation and three extras in case one fails). The U.S. military developed and implemented this satellite network as a military navigation system, but soon opened it up to everybody else.

Each of these 3,000- to 4,000-pound solar-powered satellites circles the globe at about 12,000 miles (19,300 km), making two complete rotations every day. The orbits are arranged so that at any time, anywhere on Earth, there are at least four satellites "visible" in the sky.,

A GPS receiver's job is to locate four or more of these satellites, figure out the distance to each, and use this information to deduce its own location. This operation is based on a simple mathematical principle called trilateration.GPS receiver calculates its position on earth based on the information it receives from four located satellites. This system works pretty well, but inaccuracies do pop up. For one thing, this method assumes the radio signals will make their way through the atmosphere at a consistent speed (the speed of light). In fact, the Earth's atmosphere slows the electromagnetic energy down somewhat, particularly as it goes through the ionosphere and troposphere. The delay varies depending on where you are on Earth, which means it's difficult to accurately factor this into the distance calculations. Problems can also occur when radio signals bounce off large objects, such as skyscrapers, giving a receiver the impression that a satellite is farther away than it actually is. On top of all that, satellites sometimes just send out bad almanac data, misreporting their own position.

Differential GPS (DGPS) helps correct these errors. The basic idea is to gauge GPS inaccuracy at a stationary receiver station with a known location. Since the DGPS hardware at the station already knows its own position, it can easily calculate its receiver's inaccuracy. The station then broadcasts a radio signal to all DGPS-equipped receivers in the area, providing signal correction information for that area. In general, access to this correction information makes DGPS receivers much more accurate than ordinary receivers.

#1 Garmin 880 Bluetooth Automotive GPS System w/ MSN Direct & Voice Recognition
Garmin nüvi 885/885T Bluetooth Automotive GPS System w/ MSN Direct & Voice Recognition

Garmin is currently number 1 among all GPS manufacturers among reviewers. The nüvi 885/885T is Garmin's new top-of-the-line automotive GPS and has been chosen Number 1 by the highly regarded Consumer Reports.

This state-of-the-art GPS device features a 4.3-inch, 480-by-272-pixel, WQVGA resolution screen. Its navigation is simplicity itself using am easy-to-navigate main menu with large icons for Where To and View Map. Two smaller icons at the bottom of the screen provide access to the volume controls, as well as the tools menu. If you've paired the device with a compatible Bluetooth phone, a phone icon also appears on the main screen.

There's built-in support for Microsoft's MSN Direct service. Available from the Tools menu or the Where To screen, MSN Direct provides access to a host of useful information, such as live traffic, weather, movie times, news, stock information, local events, and even gas prices at nearby service stations.

The nüvi 880 also has a number of useful built-in, travel tools, including currency and unit of measure converters, a four-zone world clock, a four-function calculator, and 11 games. You also get a music player, an Audible audiobook player, and a picture viewer. The Where Am I tool gives you your exact latitude, longitude, nearest street address, and current intersection. YOu get one-tap directions to nearby hospitals, police, and gas stations.

What makes this device special is it's sophisticated speech recognition. Garmin takes a different approach from other GPS manufacturers, however. the Magellan Maestro for example, activates its voice command mode when it hears the keyword Magellan. Unfortunately it often misinterprets passenger conversation triggering the its voice command mode. Garmin solves this problem by giving the 880 a small wireless remote designed to be strapped to the steering wheel. A large push-to-talk button on the remote puts the nüvi 880 into Listen mode, whereupon a green icon appears in the upper right-hand corner of the screen when it's your turn to speak. A red icon tells you that the device isn't accepting speech input at that moment, or didn't recognize what you've said. The smaller button on the remote takes the navigator out of Listen mode. Alternatively, after about 10 seconds of silence, the speech icon disappears and the device reverts back to normal touch-screen function.

The speech recognition abilities of the Garmin are uncanny. For those of you who use Dragon NaturallySpeaking software on your PC and have to dictate carefully in a noiseless room for any reasonable kind of accuracy probably wonder how a GPS with all of the street noise can figure out where your going. But all you need to do is activate push-to-talk button, speak your "Where to" in your usual conversational manner, and the Garmin will promote you for additional answers until it finds out what it needs. Its amazingly better as far as accuracy with picking up numbers as compared to the aforementioned NaturallySpeaking Software.

The Garmin nüvi 880 is a the best general travel GPS on the market. Features of this luxury device, including text-to-speech conversion, multisegment routing, Bluetooth plus media players and travel tools. The Garmin nüvi 880 uncannily good speech recognition blows away the competition and seals the deal.


#2 Magellan Maestro 4210 Portable Automotive GPS System 

#2 Magellan Maestro 4210 Portable Automotive GPS System

Magellan Maestro 4210 Portable Automotive GPS System


The more reasonably priced but top-of-the-line GPS is the ultra thin Magellan Maestro 4250. The Maestro comes with a 4.3-inch wide screen display, a built-in traffic receiver for live updates, and an enormous ix-million points of interest (POI) database built-in. It also t integrates with the AAA TourBook to display listings of restaurants and accommodations, local attractions, approved auto repair shops, AAA office locations, and more. This high-end model also offers text-to-speech functionality and a Bluetooth phone interface. Perhaps the most notable feature is voice command, which you can use to control many of its functions hands-free.

The Maestro 4050 let you control many of the functions with your voice. On the 4250, Voice Command works even better considering that you don't have to train the device. In fact, using Voice Command becomes quite addictive. Without an active route, the Voice Command menu can help you find the nearest coffee shop, restaurant, gas station, or ATM; navigate Home; or enter the roadside assistance menu, just to mention a few options. While not as brilliant and full-featured as the Garmin speech system, it does the job.

It also features a Bluetooth interface and pairs quickly but lacks some of the advanced features found in the Garmin such as downloading and using stored contacts from your mobile phone.

However, he most robust feature of the Maestro is its enormous database and up to date maps. Unlike other devices, all of the surrounding features are there including the newest bridges and roads. This is Magellan's top of the line GPS despite the recent of the introduction of the 5310 which has a larger screen but less features.


The Practical Uses of Global Positioning Systems (GPS) 

These are some of the ways that GPS is used in the "real world" for a variety of different purposes. In this lens we feature the "best of the breed" products in these GPS use categories

uses of gps technology

  1. GeoCaching: High Tech Treasure Hunting: Geocaching takes treasure hunting one step further by using GPS units to located hidden treasures. The name of the game is a combination of "Geo" from geography and "Caching" from the action of hiding the cache (or treasure). The term cache is commonly used among hikers and campers to refer to a hidden supply of food or other provisions.
  2. Personal Emergencies: GPS equipped cell phones can transmit precise locations to 911 dispatchers. This allows the dispatcher to have an immediate and accurate location instead of relying upon descriptions of people who may be unfamiliar with the area or too distraught to explain their location. The same technology has also helped catch people who make crank 911 calls from their GPS-enabled cell phone.
  3. Recreational Uses: GPS is popular among hikers, hunters, snowmobilers, mountain bikers, and cross-country skiers. rails can be viewed on topographic map software, traced on the screen and that route can be downloaded into the GPS. Then, in the field the route can be displayed in the map window of the GPS and easily followed. Another use is to leave the GPS on and in a mesh pocket of your backpack while hiking. This will allow the GPS to record a tracklog of your hike. The tracklog can be shared with others, plotted on maps, used for distance hiked estmiates and even printed with mapping software and shared with friends
  4. Emergency Roadside Assistance
    OnStar by GM for example uses GPS to track vehicles' whereabouts and allows motorists to summon emergency help or to ask directions.
  5. Tracking Your Kids: GPS-enabled cell phones can be used to monitor your kids. When Johnny calls you for his after school check in you can confirm if his coordinates are at the public library or at the pool ha
  6. Photography: Geocoding Photos Some cameras will annotate your digital and traditional images with the date and time, however, new GPS-enabled cameras can also annotate them with precision coordinates which mark the location of your photos. These annotations can be very useful in science field work, real estate, law enforcement and many other areas.
  7. Automobiles and Driving: GPS tracking devices can be used to navigate your car through traffic and find your way to any destination. Many Auto GPS Systems come with preloaded destination settings or points of interest (POI) that provide directions to attractions, and important pit stops such as gas stations, hotels, motels, and lodges. For vacation travel, or any other time you need to map out a course for traveling, the system has course-planning functionality.
  8. Laptop GPS: Laptop GPS receivers turn any mobile computer into a fully functional GPS System. Save money and use a laptop GPS receiver for in-vehicle, office based meetings to track locations and find directions or simply to plan a cycle ride for the next day. The in built sophistication of the laptop, augmented with navigation and mapping programs provides much more extensive information than most handheld applications. By using laptop GPS navigation, you are using an already familiar tool, with no need to learn new hardware functionality. Laptop GPS receivers are simply attached to your laptop, notebook or utlrasmall computer using USB or serial connections as with many other peripheral devices. Quite often bundled with software, they are very effective GPS systems

I have had a simple Garmin Nuvi for just a short time and it fascinates me. I just moved to a new location and the Nuvi (my pet name for it... my brother calls his 'Carmen' because his Garmin has a female voice he likes, so he named her) has been a tremendous help in finding my way around. Got really tickled with it this week -- went to a place that has a 45 degree angle road going off the main road. On the way back, it became a 90 degree turn to get back on the main road and the Garmin GPS, instead of saying "turn left" as usual, said "turn SHARPLY left". Cracked me up... I never imagined it could actually distinguish the angle of the turn.

The MySky StarTracker you showed looks really fascinating. I had no idea such a thing existed in the world of GPS. I love gadgets! Thanks for an interesting lens. 5*

#17 Parrot CK3400 LS GPS Blutooth for Cell Phone 

garmin mobile pc laptop kit

If you own a Smartphone or a PDA with navigation software, the Parrot 3400 LS-GPS Car Kit will turn your mobile device into a navigation wizard. It combines a Bluetooth hands-free kit with a color screen and a GPS antenna, and is compatible with most Bluetooth phones or PDAs.
The LCD color display screen of the 3400 LS-GPS provides the same visual information and functions as your mobile phone, such as caller ID, carrier signal strength, or last calls received, on a large, well-contrasted display that's easy to read at a glance.

Using the Parrot 3400 LS-GPS is simple. Turn on the car engine and the device synchronizes wirelessly with your phone. This allows it to not only display your phone book, but the photos you have set to correspond to certain incoming callers, as well as enabling voice recognition so you can make hands-free calls. Depending on your phone's model and firmware, most features are accessible from the hands free console, including one-touch redial, dual call, and auto-answer.

The Parrot 3400 LS-GPS makes navigation as easy as placing and receiving phone calls by constantly sending your car's position to your Smartphone or PDA. Any routes you have programmed in are calculated by your PDA and its navigation software and directions are transmitted back to you through the vehicle's speakers. You can just sit back and let your car, via your Parrot 3400 LS-GSP, tell you exactly where you are, and where you need to go.

The kit can be installed in almost any vehicle, and it's designed to automatically mute the radio while you are on the phone. Incorporating high-quality sound, the Parrot 3400 LS-GPS features echo cancellation, full duplex sound, voice recognition for up to 150 names, and hi-fi polyphonic ringtones. And when you have multiple drivers in the same car, the unit allows for up to five mobile phones to register, each with separate address book synchronization.

#18 Garmin nüvi 660 4.3-Inch Widescreen Bluetooth Portable GPS Navigator 

garmin 660
The Garmin nüvi 660 is the most elegant All-In-One GPS navigation solution I've come across to date. I belive this unit represents the best compromise between size and functionality on the market today. Beyond this point, increasing the screen size enters the diminishing return territory. The SiRFstarIII chipset, while no longer the absolute best on the market, remains a reliable workhorse with rapid satellite acquisition under even less than ideal conditions.

Garmin nüvi 660's map database features nearly six million points of interest (POIs), including hotels, restaurants, gas stations, ATMs, and attractions, and the data is provided by NAVTEQ, a world leader in premium-quality mapping.This preloaded navigator brings all this fantastic map data to your fingertips with a super-bright, 4.3-inch widescreen display for improved map viewing, day or night. Use the touch screen interface to select destinations, look up POIs, and play your favorite MP3s and audio books. The display also helps you control hands-free calling, traffic alerts, and the FM transmitter, all from the screen of your personal travel assistant.

The voice prompts are loud, clear and timely. The ease of use is just fantastic and the visibility and quality of the It uses the same low reflection screen as the 360.

POI access is excellent and can be navigated to much more simply than the TomTom unit which requires additional cumbersome steps. The attachment system for the Nuvi is superb and very secure. You can access your POIs directly by name rather than having to go through a cumbersome category menu and then only getting the POIs by proximity as is the case with the TomTom 910. Garmin simply blows TomTom away in the POI functionality department.

Some features include:

WideScreen Format: This Garmin's display is now the gold standard in the industry with a 4.3" WQVGA LCD screen and 480 x 272 pixels. The widescreen format gives you 70% more actual screen area than a 3.5-inch screen. Primarily this translates into a better view of the area through which you are driving. This is especially useful in showing you what parks, restaurants, ATM, gas stations, etc. are nearby, or in letting you know whether a detour is a good idea. Also, the device itself is larger, meaning controls on the screen are more widely spaced and somewhat easier to push.

FM Transmitter: Instead of straining your ears to hear turn-by-turn directions or your favorite MP3s, you can enjoy wireless FM audio transmission via the nüvi 660's wireless FM transmitter. Tune your car's radio to the appropriate station and you'll hear all the nüvi's audio, including voice prompts, MP3s, audio books, and more, directly through your vehicle's stereo system. The nüvi 660 includes many "must-have" entertainment and travel tools, including digital music and audio book playback, JPEG picture viewer, currency converters, and more. All these great features make the nüvi 660 a complete Personal Travel Assistant.
