I’ve read the wikipedia.com entry for GPS and some of it just doesn’t gel with me.

Anyone have any pointers to a description online on how most gps receivers can calculate the correct time that an interested “newbie” would appreciate?

I’m also interested how a gps receiver can discriminate satellites’ C/A trains with multiple radios when all satellites are transmitting at the same frequency? Wouldn’t all the radios (like on a 12-radio GPS receiver) be listening to exactly the same thing? Seems like they’d all be stepping on themselves and not be separable.

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.

Taiwan GPS Receiver Market

In Taiwan, GPS suppliers besides taking over most international companies’ orders, also successfully develop GPS watches for hiking, golfing and cycling.  GPS receiver navigation devices have developed rapidly in recent years and are now much more than talking maps. Auto electronics, consumer electronics, home appliances, information and communications technology (ICT), and telecoms companies have worked together to give them a much more diverse range of functions including use in those of MP3 players, digital photo albums, movie players, and real-time road-condition receivers. They now provide information on navigation, recreation, and entertainment, all in a single unit.

Taiwan’s GPS industry started to take off in 2007. After MiTAC bought Navman, they’ve become the second biggest GPS company in Europe. Also, their sales of 800 million of PND has made them become the third largest GPS supplier in the world. At the same time, TomTom and Garmin have expended their ordering to Taiwan OEM’s from components to fabrication products. The global leader in satellite navigation, Garmin Ltd. and its subsidiaries have designed, manufactured, marketed and sold navigation, communication and information devices and applications since 1989 – most of which are enabled byGPS technology. One of their principal subsidiaries is located in Taiwan. Including Japanese and European orders, Taiwan’s GPS sales were around NT$171 billion. The total growth rate was 70%, which makes its growth very noticeable compared to the 2007 ICT industry growth rate of 4.6%, or 730 billion dollars.

Even though this year, European and U.S. consumer electronic product sales are still being effected by the current economy situation, IEK is still very pretty positive about the GPS market in Taiwan. The Taiwan GPS industry market will grow strongly once the market moves from Europe and the, U.S. to the newly developed countries.

GPS for Hiking

What’s a suitable GPS for cycling? Color mapping, long life battery or replaceable batteries, topo, street/road, & bike trail mapping, text-to-speech (gives me the street name), prefer selectable car vs bicycle mode, a way to pick future routes, possibly software that would use steet & topo to avoid large hilly areas on long distance biking, large SD card, fairly waterproof, screen can be seen in sunlight. One of the Taiwan GPS receiver suppliers announced their product as an all-in-one GPS receiver.

Dedicated massive-correlator signal parameter search engine within the baseband enables rapid search of all the available satellites and acquisition of very weak signal. An advanced track engine allows weak signal tracking and positioning in harsh environments such as urban canyons and under deep foliage.

With very fast signal acquisition speed, it has very low average power consumption for locate on demand type of applications.

GPS for Golfing

Golf GPS systems are rapidly evolving from only player enhancement to complete course management systems. The primary goal of a golf GPS system is to provide players with distances to all kind of features on the course and especially to the green they are playing. Some courses are better fit to use the capabilities of GPS than others. In order to obtain a satisfactory accuracy the GPS receiver must have a non-obstructed view of the sky. This makes that courses with lots of trees are less suitable for golf GPS.

Golf GPS system should contain the following:

Provides you with GPS distances from “any” location on the hole to the 200, 150, 100 yard / meter markers, to the front, centre, and back of the Green.

Record the GPS distance, club used and landing position for every stroke you make.

Stroke length Statistics: tells you the average and longest distance you hit each club in your bag. You know exactly how far you drive the ball.

Club Selector! Suggest which club to use for your next stroke based on the historical stroke data already stored from previous scorecards!

Taiwan GPS suppliers, Mobile Action Technology Inc and Polar have released their new GSP products for sport.

GPS for Cycling

Whether you are a road biker or a mountain biker, there’s a GPS that will work well for you, and it can mount right on your handlebars. All of them have high-sensitivity chipsets for superior satellite reception in urban canyons and under canopy. While they are excellent cyclometers, they aren’t all that great as navigation devices. If you are primarily wanting to track your performance though, Taiwan suppliers who make sporting GPS receivers would be your excellent choice. They are suitable for whoever wants data acquisition and a dashboard lap timer.
