Learn the basic and important Principles Behind GPS Tracking


The United States Air Force's 50th Space Wing is currently in charge of maintaining the 24 satellites that make up the Global Positioning System (GPS). To communicate with Earth, each satellite uses microwave waves. Global positioning system (GPS) receivers on the ground interpret these signals to compute their coordinates, velocity, heading, and elapsed time. Line-of-sight is required for a standard GPS receiver to triangulate its location using signals from four or more satellites. The procedure requires a highly precise local time for the gadget to detect both its time and position, hence four satellites are required.

·         The fleet management system can then use this location data to service the end customers. This is accomplished by the wireless transmission of the data to a server.

·         The Global Positioning System (GPS) transmits signals to Earth continuously. These transmissions are received by a GPS unit installed into a vehicle or other asset. The device then uses geometry to calculate its position from the satellite signals it receives.

·         Additional communications features can be added via optional inputs as a message display terminal, personal navigation device, or PTO sensors.

·         Then, the gadget serves as a wireless modem, sending data such as position, velocity, and course via the cellular network along with any other messages.

·         Incoming data is processed and stored on servers.

·         A user can check the whereabouts and history of their vehicles and other assets by logging into a website.

The receiver processes the signals to derive the position (latitude and longitude), velocity (speed), and height (altitude above sea level), as well as the time. This data set is sent over a wireless network to a server for use in fleet management systems at falcontrackers. The server then processes the information to deliver accurate location information to the user.
