Embodiment

[0046] A ground testing method for a high-orbit satellite navigation receiver, the steps of the method comprising:

[0047] The first step is to design a test case sequence composed of on-board operation instructions and operation instructions of the mathematical orbit simulation module according to the set requirements. The currently established and solidified test case sequence for high-orbit satellite testing includes high-orbit satellite navigation receiver startup use cases, high-orbit satellite navigation receiver shutdown use cases, high-orbit satellite orbit simulation flight use cases, high-orbit satellite active segment simulation use cases And high-orbit satellite mission time-hopping use cases. Taking a part of the interception in the high-orbit satellite navigation receiver start-up use case as an example, see image 3 ;

[0048] In the second step, the functional automation test case module executes the content of the use case. First, it receives the satellite ...

Abstract

The invention relates to a ground test system and method of a high-orbit satellite navigation receiver, belongs to a ground test system of a spacecraft comprehensive test, is particularly suitable for realizing the ground test system of the navigation receiver of a high-orbit satellite, has the capability of simulating and generating a high-orbit navigation signal, and is used for testing the high-orbit navigation receiver. And the integrated, automatic and universal design of the system is fully considered. According to the system, a function automation test case module and a data packet automatic interpretation module are adopted to solve the problems of low systematic comprehensive test efficiency and high dependence on people at present. And an automatic, integrated and universal test system is designed to realize subsystem test production line and process. The interpretation report is automatically generated to solve the long-term interpretation problem of large data volume, the test period is shortened, and the cost is reduced.
