How does GPS tracking work?
Wednesday, March 26th, 2008For GPS tracking to work, you need access to the Global Positioning System and a GPS receiver. The GPS receiver receives signals that are transmitted by more than two dozen GPS satellites that orbit earth. Once these satellite transmissions are received-location, speed, direction and other information can be calculated.
GPS tracking is a term used to determine the location of a person, vehicle or any other asset using the Global Positioning System. Usually, “locates” are recorded at regular intervals.
Recording information from the tracked unit takes place within the GPS receiver unit, or it can be transmitted to a central location such as a database. The information can be accessed either via mobile phone technology or over the Internet. GPS tracking units can use cellular GPRS, satellite modem technology or radio waves to transmit information to a central location where the data is logged and recorded.
Most GPS tracking systems can be viewed in real time and have a map in the background to easily display the current location of an object.
Overall, the process is pretty simple. Satellite to device to your personal computer or PDA; GPS brings you a plethora of pinpoint accurate information in seconds.
