Design and Realization of a GNSS Receiver Test Equipment

Due to the high cost of the traditional GNSS receiver testing by an analog signal source of satellite navigation signals, a test equipment is designed based on the rapid signal detection toward the sky and the online automatic test method of interface signals, so as to realize the tests of overall positioning accuracy test and fault diagnosis of GNSS receivers. It has the features of rapid testing, ease for use and good practicability, thus reducing the test cost of GNSS receiver testing.
