摘要
A pseudo-satellite transmitter includes a GPS unit, a transmission power control unit, and a plurality of antennas. The GPS unit generates a GPS signal of a pseudo-satellite. The transmission power control unit generates a plurality of GPS signals having different power levels based on the GPS signal generated by the GPS unit and a distance from a shadow area to the pseudo-satellite transmitter. Each antenna is configured to wirelessly transmit the GPS signals with different power levels output from the transmission power control unit to a corresponding one of a plurality of shadow areas according to the distance from the shadow area to the corresponding antenna.
