What is gps used for

Episode seven of our Introduction to GNSS series explains how satellite positioning supports these three unique applications. Hexagon NovAtel is a leading provider of precise global positioning system and augmentation technologies designed to afford its customers rapid integration and exceptional return on investment. All NovAtel receivers offer the ability to unlock additional functionality as system requirements evolve with field-upgradeable software. Certain receivers also feature the optional Application Programming Interface API for the development of specialized onboard applications.

What is GPS used for today? What is CAD Software? What is GIS? What Are Enabling Works? What Are Bulk Earth Works? What is Civil Construction? What is a Re-Establishment Survey? What is a Detail Survey? What is a Set-Out Survey? The achievable accuracy depends on the status of the user.

For military purposes and some specific civil ones , one metre or better in all three coordinates longitude, latitude, altitude can be reached. For common civil users, the full accuracy of the coded satellite signal cannot be exploited, but it is still possible to reach an accuracy of about 15 metres in the best cases. A good GPS receiver is now cheaper than a mobile telephone. While it is great fun to use a GPS receiver during hiking trips etc.

Virtually all civil aircraft are now equipped with GPS. This allows the pilot to know the position of the aircraft and by continuously plotting this position on a computer map, to follow the progress of the flight along the chosen route. Scouting Events K Outreach. The G lobal P ositioning S ystem GPS is a satellite-based navigation system made up of a network of more than 24 satellites placed into orbit by the U.

Department of Defense. GPS was originally intended for military applications, but in the s, the government made the system available for civilian use. GPS works in any weather conditions, anywhere in the world, 24 hours a day. There are no subscription fees or setup charges to use GPS. How it Works GPS satellites circle the earth twice a day in a very precise orbit and transmit signal information to earth.

GPS receivers take this information and use triangulation to calculate the user's exact location. Essentially, the GPS receiver compares the time a signal was transmitted by a satellite with the time it was received. The time difference tells the GPS receiver how far away the satellite is. Now, with distance measurements from a few more satellites, the receiver can determine the user's position and display it on the unit's electronic map.
