GNSS技术在飞速发展中，用户对GNSS接收机性能的要求也在提升。不同

With the rapid development of GNSS technology, users' requirements for GNSS receiver performance are also increasing. The performance and measurement accuracy of different receivers are not completely consistent, and the performance of the GNSS receiver needs to be tested. Based on the performance indicators of three GNSS receivers, Leica GX1230, Leica GS15, and Trimble 5700, the paper analyzes the performance test conditions and finds that Trimble 5700 has the advantage in reacquisition time, Leica GS15 has the advantage in anti-interference ability, and the positioning accuracy , Dynamic positioning accuracy Leica GS15 dominates, static positioning accuracy is the same.

GNSS technology is developing rapidly, and the user's demand for GNSS receiver performance is also increasing. The performance and measurement accuracy of different receivers are not exactly the same and the performance of GNSS receivers needs to be tested. In this paper, the performance index of Leica GX1230, Leica GS15 and Trimble 5700 GNSS receivers is analyzed, and the performance test conditions are analyzed, and the results show that Trimble 5700 is superior in re-capture time, Leica GS15 is superior in anti-jamming capability, and the dynamic positioning accuracy Leica GS15 is superior and static positioning accuracy is the same.

With the rapid development of GNSS technology, users' requirements for GNSS receiver performance are also improving. The performance and measurement accuracy of different receivers are not completely consistent, so it is necessary to test the performance of GNSS receiver. According to the performance index of Leica gx1230, Leica gs15 and Trimble 5700, this paper analyzes the performance test conditions, and concludes that Trimble 5700 is dominant in recapture time, Leica gs15 is dominant in anti-jamming ability, and Leica gs15 is dominant in positioning accuracy, Leica gs15 is dominant in dynamic positioning accuracy, and the same in static positioning accuracy.<br>
