Abstract:
Provided is a Global Positioning System (GPS) signal repeater and a GPS receiver of a stationary orbit satellite, and a method for positioning a stationary orbit satellite using the same. The GPS signal repeater includes: a GPS receiver for receiving an L-band GPS signal transmitted from a GPS satellite; a low-noise amplifier for removing noise of the received L-band GPS signal and maximally amplifying a desired signal; a frequency transformer for transforming the amplified L-band GPS signal into an up-link frequency band; a high power amplifier for amplifying the transformed up-link frequency band GPS signal; and a transmitter for transmitting the amplified signal to a stationary orbit satellite.
