Design and implementation of a GNSS navigation terminal automation test system

In order to solve the problem that it is impossible to carry out multi-scene and multi-station tests for satellite navigation terminal in the market, an automatic test system is developed. By integrating multiple test scenes and multiple test sources, multiple navigation terminals can be tested simultaneously. The test system is classified and constructed according to hardware and software, and the data flow and control command flow among subsystems are introduced. Based on the concept of functional modular design, the test system uses Qt to develop the test software. Finally, a commercial navigation terminal is taken as an example to verify the test system. The satellite navigation terminal test system constructed by multi-source and multi-scene test method has high test efficiency and the test results prove that the test system is reliable.
