GPS is a passive satellite navigation system. In the passive ranging system, the user antenna only needs to receive navigation positioning signals from these satellites, so as to measure the distance or difference between the user antenna to satellite. This kind of distance -ranging signal and receiving ranging signal ranked in two different places, which are called passive ranging. With the standing star distance it measured and using the known satellite at the orbit position, the three -dimensional location of the user antenna can be calculated. This positioning based on passive ranging principle is called passive positioning. If the ranging signal transmitted by the sending device is reflected or reposted by the reflex, returned to the sending point to receive the receiving equipment, and then measure the distance experienced by the ranging signal. The ranging principle of sending and receiving ranging signals is located in the same place in the same place, called active ranging. With the standing distance it measured and the known satellite in the orbit position, the current three -dimensional location of the user can be calculated. This position based on the principle of active ranging is called active positioning
