导航信号采集回放测试系统设计与实现

Design and implementation of navigation signal acquisition and playback test system

导航信号采集回放测试系统避免了实验室仿真环境测试与实星环境测试结果的差异问题,兼顾了系统使用的便捷性和可重复性。此外,导航信号采集回放测试系统解决了授权信号等特殊场景的测试问题,有很强的适用性。经试验验证导航终端实星环境与采集回放测试系统下的测试结果基本一致,充分论证了导航信号采集回放测试系统的可行性。

The navigation signal acquisition and playback test system of this paper,which can be used to avoid the difference between the laboratory simulate test and the real star test results,is taken into account both the convenience and repeatability.Furthermore,with great applicability,the system can solve the problems such as authorized signals when testing in special scenes.Experiments verify that the test results of the navigation terminal real star environment are consistent with the results under acquisition and playback test system,which fully demonstrates the feasibility of the system.
