| 随着我国自主设计的北斗卫星导航系统稳步建设和发展，北斗接收机相关技术取得突破，但当前北斗接收机校准体系尚不完善，相关测试方法亟待研究。本文提出基于卫星导航信号模拟仿真测试法，通过多星座导航信号模拟器设计静态、动态等仿真场景模拟相关载体运动状态下真实的卫星信号，实现对北斗接收机在相关载体运动状态下导航精度的校准测试。该方法具有准确度高、简单易操作和重复性强等优点，可实现实验室条件全面检测接收机性能。实验结果表明：北斗系统的定位和测速精度已基本接近GPS系统，但就系统的稳定性，北斗系统与GPS系统相比还存在一定差距。 |

| With the steady construction and development of BeiDou Navigation Satellite System, the related technology of BeiDou receivers has made a breakthrough. The current calibration system of BeiDou receivers is not perfect, and the relevant methods must be studied. This paper proposes a simulation test based on satellite navigation signal. Through the multi constellation navigation signal simulator, static and dynamic scenarios were designed to simulate the movement of real satellite navigation signals. The method can realize a calibration test of BeiDou receivers’ navigation precision in different carriers. The method can not only take the advantages of high accuracy, easy operation and repeatability, but also can realize the comprehensive testing of BeiDou receivers in the laboratory condition. The experimental results show that the measurement accuracy of position and velocity in BeiDou has been basically closed to GPS’s, but there is a certain gap on the stability between BeiDou and GPS. |
