EGSE Performance Verification of Navigation Receiver Using Ground Test System EGSE for Verification of Precision Navigation Performance of Satellite Navigation Receiver for Low Earth Orbit Satellite

摘要

In the present invention, a method for constructing a ground test apparatus (EGSE) for verifying precision navigation performance of a low-orbit satellite navigation receiver is based on a reference navigation system using RF splitters to receive received RF signals in constructing an EGSE system for verifying performance of a low-orbit satellite navigation receiver. Simultaneously connecting to a receiver, a target navigation receiver, an RF data collection device, configuring an RF collection device to receive satellite RF signals and to store source data in connection to the RF data collection device; Storing the time synchronization signal of the RF collection device in the RF data acquisition server using the time synchronization information of the navigation receiver, and after the step, the EGSE software collects the navigation data processing results of the reference navigation receiver and the target navigation receiver and the RF source collected Compare the data to verify the performance of the navigation receiver And a step of applying. In the present invention, when developing a satellite navigation receiver used as a navigation device of a low-orbiting satellite, it is necessary to verify the performance of the navigation receiver on the ground, and in this case, the performance of the reference navigation receiver itself is verified in using the reference navigation receiver. In order to test more advanced performance, we actually need a way to compare the signal received by the navigation receivers. According to the present invention, the performance of navigation receivers can be compared with the RF source data, and thus, more reliable and accurate verification results can be obtained than conventional EGSE test and verification methods.
