Patent ID: 7826994

Claim:
A global position system (GPS) module test system for calibrating a test signal, applicable to automatically gain a GPS test signal for testing whether a GPS module under test operates normally, the GPS module test system comprising: a GPS test fixture, for carrying and electrically connecting the GPS module under test through contact, and receiving a digital signal generated by the GPS module under test; a satellite signal simulator, for generating and transmitting a GPS test signal to the GPS module under test; and a computer, connected to the GPS test fixture and the satellite signal simulator through a signal cable respectively, for performing the following steps: receiving a device information of the GPS module under test transmitted by the GPS test fixture, and finding a corresponding standard test signal parameter from a GPS signal sample database; according to the standard test signal parameter, controlling the satellite signal simulator to generate the GPS test signal to test the GPS module under test; receiving the digital signal of the GPS module under test, and automatically gaining a preset test parameter to a level when the digital signal is attenuated; and controlling the satellite signal simulator with the gained preset test parameter to calibrate the GPS test signal through auto gain.
