GPS Ⅲ系统操作概念初探

GPS Ⅲ System Operations Concept

GPS Ⅲ系统将改变现有操作方式，利用新型的高速上行／下行链路和交叉链路通信结构提高操作人员的能力。由于可以连续连通，操作员可以实现“一颗卫星通，所有卫星通”的操作概念，从而实现近实时的导航更新和遥测监视。本文介绍了洛．马公司提出的GPS Ⅲ系统的操作概念，探讨了对卫星操作可能进行的改进，包括：星座监视、指挥和控制、导航上载监视、全球服务监视、全球服务预测、异常检测及实现方法。

The GPS Ⅲ system changes existing operational paradigms. Operator capabilities are improved by a new high - speed uplink/downlink and crosslink communication architecture. Continuous connectivity allows operators a ＂contact one satellite - contact all satellites＂ concept enabling near - real - time navigation updates and telemetry monitoring. The paper describes the potential improvements for the following operations： constellation monitoring, command and control, navigation upload monitoring, global service monitoring, global service prediction and anomaly detection and resolution.
