卫星通信传统上直接依赖星地联试系统进行其有效性验证,导致成本、时间代价均较大。首先,提出基于地面集成模拟验证系统(简称“小系统”)的卫星通信创新测试验证方法,并以5G非地面网络(NTN)体制为例建立测试验证环境、设计测试验证方案以及开展测试验证。其次,论证卫星通信测试验证中“小系统”从无到有的价值,不仅对系统设计的正确性起到先行验证的作用,从而降低星地联试风险,而且相对于传统测试验证方法明显提升了验证效率。
Traditionally satellite communications have relied directly on the full system construction with satellite and ground elements (called "large-scale system") for verification of their effectiveness
resulting in high cost and long time period. Firstly this paper proposed an innovative test verification method for satellite communications based on the ground integrated monitoring verification system (called "small-scale system"). Took 5G NTN system as an example
it established related test environment
designed verification solutions
and conducted a series of key test examples. Secondly
the value of "small-scale system" introduced in the process of satellite communication test was demonstrated to be very useful
which not only acts as a pre-verification of the correctness of system design and thus reduced the risk of large-scale system test
but also significantly improved the verification efficiency compared to traditional test verification methods.
