观测条件较差的情况下，单系统卫星可见性不佳，导航定位精度降低甚至无法定位。而组合卫星导航系统增加了可见卫星数，可以改善定位结果。我国自主建设的北斗卫星导航系统现已具有初步导航定位能力，可与其他导航定位系统兼容。测试是定位软件开发中不可缺少的一部分，目的是发现并排除软件中潜藏的错误，从而满足产品的设计要求和提高软件的质量。本文详细介绍了GPS北斗联合差分定位软件的测试方案，以移动测试为例介绍了测试的实施流程，并针对设计要求给出了成果评价指标。

Under poor observation conditions, single navigation system usually has lower visibility and declined positioning accuracy. Combined navigation system can improve the satellite visibility and improve positioning accuracy. Beidou navigation system has already been available for primary navigation and positioning. Test is an indispensable part in the development of positioning software. Its goal is to find and eliminate potential errors in the software, so as to improve software quality and meet the design and requirements. We introduce a test program of GPS and Beidou positioning software with an example of actual test. Achievement evaluation index has been given in the paper according to the design demand.
