With the development of the satellite radio navigation system, BeiDou-1 user equipments have found wide application. The capability of those equipments consequently attracts more attention. A practical solution to test those devices is to design a automatic test system aiming at the special test requirement. A simple introduction of BeiDou-1 Navigation System and the test requirement of its user equipments is given, followed by the ATE design in detail, including the system structure, implementation of navigation signal emulator, signal and data process, etc. Test result shows that the ATE presented can meet the requirement to test and verify the performance of the user equipments well.
