摘要： 北斗卫星导航系统是一个构成庞大、星地一体紧密耦合、建设周期长、技术状态不断演进的巨系统。面临着关键技术体制复杂、组网发射密度高、系统稳定运行难度大等多方面挑战，对系统的试验验证工作提出了极高的要求。本文分析了北斗系统在设计试验、星地对接及等效运行等方面试验验证任务，提出了一个与北斗系统全系统、全规模、全要素等效的地面试验验证系统体系架构。该系统具备软硬件平台协同工作、仿真系统与真实系统的等效运行，以及试验平台与卫星地面等系统远程互联等突出特点，解决了多系统仿真建模、系统高动态特性模拟及软硬件协同仿真等难题，实现了对北斗系统设计、建设与运行阶段的全过程验证，以及对北斗系统星间链路、卫星自主完好性及精密定轨等技术体制的试验验证。本文提出的系统是目前卫星导航领域唯一一个实现系统全状态仿真、能与真实系统同步迭代演进并协同运行的试验验证系统，可为其他航天任务的试验验证工作提供参考。

Abstract: The BeiDou Navigation Satellite System (BDS) is a constantly-updated huge system with tightly-coupled space and ground segments and long construction period. Faced with the multiple challenges of highly complicated key technical scheme, high-intensity satellite deployment and launching tasks, and high difficulty in system stable operation, BDS has very high demands for the system's test and verification. This paper analyzes the test and verification tasks of BDS including system design and verification, space and ground segment integration, and simulation operation, and proposes the system architecture of the ground test and verification bed which equivalent to the full-system, full-scale and full-elements BDS. The bed is featured with synchronized work of the software and hardware platforms, equivalent operation of the simulation and real systems, and remote connection between the test bed and system segments, and solves the problems of multi-system simulation modeling, high-dynamic simulation as well as software and hardware synchronized simulation; realizes the whole process verification of the BDS design, deployment and operation, and also realizes the test and verification of the BDS new technical schemes such as inter-satellite links, BDS satellite autonomous integrity monitoring, and precise orbit determination. The bed for BDS is the only test and verification system in the field of satellite navigation that can realize all-states system simulation, and synchronized iterative evolution and operation with the real system, and can serve as important reference for the verification work of other space missions.

Key words: BDS, test and verification, system architecture, simulation modeling
