A method and system for testing GPS OTA, comprising: placing a terminal to be tested on a turntable in an anechoic chamber, and generating a GPS signal in the anechoic chamber by means of a GPS satellite signal generator (S101); acquiring the satellite signal strength of each angle and polarisation direction and generating a signal strength pattern (S103); finding the best angle and polarisation direction and acquiring the corresponding sensitivity (S104); on the basis of the signal strength pattern and the sensitivity of the best angle and polarisation direction, acquiring the sensitivity of each angle and polarisation direction (S105) and integrating these to obtain the antenna signal strength (S106). The present testing method and system can shorten testing time and improve testing efficiency, simplify testing systems, and reduce costs. |
