A Framework of Ground Test and Verification for Inter-Satellite Links Communication Based on Virtual and Physical Combined Technique

建立地面试验验证环境是降低星间链路技术风险的有效途径。针对导航卫星组网功能和性能的测试问题,本文提出一种星间链路组网地面试验验证框架。该框架根据星间链路信息处理流程,设计基于虚(虚拟卫星)实(实际卫星)结合的星地试验方案,并采用正交试验测试技术测试组网算法。通过对星间链路试验场景和试验方法的设计,实现对星间链路组网功能和性能的测试与评估分析。结果表明,该框架能满足单星网络接入、整网组网测试等地面试验验证需求,为降低地面试验成本和风险提供了一种可行方案。

Building a ground test and verification experiment environment is an effective way to reduce the risk of the inter-satellite links （ISLs） technology. In this paper, a test and verification framework of ISLs communication protocol is implemented , which is aimed at figuring out the networking testing and verifica- tion problems of function and performance. More specifically, based on the real ISLs information process- ing, a scheme consisted of virtual and real satellites is created, which takes orthogonal test as communica- tion protocol verification method of ISLs. Through scenes and methods design of ISLs, a test and an evalua- tion analysis method are developed. As the results of performance, this framework is a feasible scheme, which possesses low cost and low risk, and totally meets the ground test and verification requirements of sig- nal satellite accessing and communication protocol testing.
