Get on the fast track with global positioning systems
Learn all about satellite receivers and how they work to help you. Global positioning systems are perfect navigation devices for your car or truck.
With portable navigation systems, you can use the accuracy of global positioning systems any where you go. From camping outdoors to verifying an exact route, satellite receivers are the wave of the future.
With this awesome online guide to global positioning systems, you will find a wealth of information about economical navigation systems, satellite receivers and digital road maps.

GPS technology is a navigation system that utilizes radio-waves to calculate exact land, sea or air positions anywhere in the world.
The Global Positioning System operates via 24 satellites, which are monitored daily by their ground stations.
There are five basic steps to the operation of GPS, which are:
- Measure Distance
- Accurate Timing
- Satellite Positions
- Checking Errors
Triangulation is the means of which the GPS receiver measures exact distance via traveling radio waves.
It does this through the utilization of three to four satellites, which broadcasts their exact positions. Finally, the GPS receiver calculates the difference in measurement to complete the process of triangulation.
Measurments are based on the time it takes for the GPS radio wave to correspond. An accurate measurement of distance to the satellite can then be calculated.
Pseudo-random codes have been generated as the GPS language of measurement. Once the GPS receiver multiples the travel time by the speed of light, it provides accurate distance measurements.
Due to the importance of getting accurate timing, grounding stations monitor satellites on a daily basis. New orbit positions are broadcasted twice a day by the Department of Defense.
Areas of error in the GPS system are constantly being factored into the navigating tools.
From the very early days of sophisticated society, navigation has been of importance.
In fact, finding position points on the earth with the help of the stars, has evolved naturally over the centuries into the new technologies we see today, like GPS.
GPS is just an easier and faster way to navigate and locate all the things we have always done by hand.
Finding out where you are on the planet is critical to so many functions of today’s society, including:
- Maps & Routes
- Tracking Transportation
GPS was originally created for the U.S military, allowing them to track flight planes, lost sea vessels and military movement.
Ecology is easily tracked with the use of GPS technology. For instance, civilian plots of farmland can be navigated for crop-dusting, surveying and aerial photography.
Imagine the time that can be saved in the car by zeroing in on an accurate destination point, and having the route outlined for you.
Emergency vehicles, trucking services and cars can all benefit from the mapping systems of GPS. This also includes tracking transportation and shipping of major exporting companies.
Another great benefit to the GPS system is its hand in advancing telecommunications. The synchronization of digital networks can be enhanced with this accurate technology.
Measuring and monitoring the earth for earthquakes and forest fires can greatly aid in maintaining and controlling natural disasters.
While GPS system contribute to the function of our society as a whole, it also has some practical, everyday uses.
New integrated circuit technology has allowed GPS receivers to become portable and economical. In fact most consumer GPS receivers can be installed in your radio, computer, laptop, cell phone or come as handheld devices.
Using GPS receivers in your car, boat, plane, machinery, or equipment is handy and convenient. Here’s a look at some smart ways to use GPS systems on a daily basis:
- Outdoors –hiking & camping
- Athletics –training & recording
- Vehicles –tracking & navigating
You can find hand held GPS devices in many lightweight forms, from waterproof receivers for the outdoors to wrist receivers for the serious jogger, you can get your GPS in one compact form.
Don’t forget that navigation in your car can be simple with mapping and route design GPS systems. Radio waves can be downloaded directly into your radio, PC, laptop or cell phone with miniature GPS receivers.
