Patent ID: 7649493

Claim:
A GPS signal transmitting system for transmitting a signal by combining a GPS signal received by a GPS antenna with a satellite signal received by a satellite antenna, comprising: a first line transmitting the GPS signal output from said GPS antenna; a second line transmitting the satellite signal output from said satellite antenna; a mixer unit connected to the first line and the second line to combine the GPS signal with the satellite signal to output a combined signal, said mixer unit including an up-converter to up-convert the frequency of the GPS signal sent out from said GPS antenna, and a generator combining the GPS signal output from the up-converter with the satellite signal sent out from said satellite antenna to generate a signal; a third line transmitting a signal output from the generator; a separator to separate the signal transmitted via the third line into the GPS signal and the satellite signal; a down-converter to down-convert the frequency of the GPS signal separated by said separator; and a transmitter to transmit the GPS signal based on the output from said down-converter.
