星上实时处理半实物测试系统的设计与实现

Design and implementation of on⁃board real⁃time processing hardware⁃in⁃the⁃loop test system

国产高性能处理芯片在卫星产品中的广泛应用,促进了星上实时处理技术的快速发展,同时对地面测试和验证系统的有效性提出了较高要求。针对卫星有效载荷分系统星上实时处理的需求,构建了以星上实时处理半实物系统为主体的测试环境,用于星上嵌入式软件开发的仿真验证,并自动地对处理结果进行对比和分析,完成效果评估,为卫星在轨可靠运行提供支撑。

The wide application of domestic high performance processing chips in satellite products promotes the rapid development of on-board real-time processing technology,and puts forward higher requirements for the effectiveness of ground testing and verification systems.Aiming at the requirement of on-board real-time process⁃ing for satellite payload sub-system,a test environment with on-board real-time processing hardware-in-the-loop system as the main body is constructed for the simulation verification of on-board embedded software develop⁃ment,and the processing results are compared and analyzed automatically to complete the effect evaluation,which provided support for the reliable operation of the satellite in orbit.
