GPS signal repeater and GPS receiver of stationary orbit satellite, and method for positioning stationary orbit satellite using the same
First Claim
1. A Global Positioning System (GPS) receiver of a stationary orbit satellite, comprising:
- a low-noise amplifying means for removing noise from an up-link frequency band GPS signal transmitted to the stationary orbit satellite and maximally amplifying a desired signal;
a frequency band dividing means for dividing the amplified signal into a plurality of signals each having a unique frequency bands;
a GPS signal creating means for creating the divided signals as L-band GPS signals; and
a position calculating means for selecting a GPS satellite among the L-band GPS signals and calculating a position of a stationary orbit satellite based on information on the GPS satellites and radio wave time of flight of the GPS satellites,wherein the up-link frequency band GPS signal excludes a frequency band of the L-band GPS signal to avoid interference of the L-band GPS signal.
