摘要
针对新一代卫星导航系统发展趋势,围绕大规模低轨星座的导航增强性能评估需求,对仿真系统进行特点分析,设计新一代低轨巨星座导航增强系统数字仿真试验平台。攻克了弹性可演进系统总体架构设计、全要素高逼真系统对象数字化建模、大规模多节点加速仿真引擎等关键技术。该系统可用于低轨星座导航增强业务仿真试验,为新一代基于低轨星座的导航增强体制设计、全链路信息协议验证、导航服务性能提升试验等提供有力支撑。
In response to the development trend of the new generation of satellite navigation systems,and focusing on the requirements for evaluating the performance of navigation augmentation based on large-scale LEO constellations,a digital simulation test platform for the new generation LEO giant constellation navigation enhancement system was designed.The platform addresses key technologies,such as the overall architecture design for elastic and evolvable systems,digital modeling of full-element high-fidelity system objects,and large-scale multi-node accelerated simulation engines.This system can be used for simulation tests of LEO constellation navigation augmentation services,providing strong support for the design of a new generation of LEO constellation-based navigation augmentation systems,the verification of information protocols,and the improvement of navigation service performance.
