- The United States Department of defense. A SA satellite signal to interference (the U.S. government for consideration of security of civil code of a called "selective availability (Selective SA Availability)" interference, to ensure the best protection system is effective. Because of the random error information added by SA in the navigation message, the positioning accuracy of the civil signal C/A code is reduced to about 100 meters. However, the use of differential GPS technology, the system error can be reduced to 10 to 15 metersTwo. Weather factors (including sunspots, bad weather, etc.) to reduce the intensity of the received signalThree. In buildings, vehicles, insulation paper, or metal shielding, GPS signal will be reduced or completely lost signal. In open spaces, GPS devices receive the best signal. .

The DGPS transmitter is a fixed GPS receiver (in a 100km ~ 200km exploration scene in the radius setting) receive satellite signals, it knows exactly what is the exact time of transmitting satellite signal to the theory, and then compare it with the actual delivery time, then calculate the "difference", influence this is very close to the atmospheric refraction, it will send out the difference, usually with FM (FM) radio data transmission using subcarrier modulation signal in the baseband receiver, GPS and DGPS function can receive and use it more accurate positioning.
