A GPS tracking device calculates its position by measuring distances between itself and other GPS satellites. In return, the signals emitted by the satellites carry information about the GPS carrier’s location. Aside from absolute location, other civilian benefits from having GPS vehicle tracking devices include relative movement. Relative movement is useful in ships and vessels to calculate certain time distance calculations including velocity made good toward your destination and crosstrac error calculations. (more…)
