摘要

本文介绍了一种以伽利略为参考，用于通用GNSS星座设计优化的系统工程工具。优化是通过考虑全球覆盖的百分比和位置确定的准确性来执行的。该工具不仅可以对标称和理想情况进行优化，还可以对涉及星座卫星灾难性或瞬态故障的非标称配置进行优化。GNSS对故障的鲁棒性分析大大改变了在标称条件下设计的原始配置中每平面使用的卫星数量。

A System Engineering Tool for the Optimisation of a GNSS Constellation Design

This paper introduces a system engineering tool for the optimisation of a generic GNSS constellation design by using Galileo as reference. The optimisation is performed by taking into account both the percentage of global coverage and the accuracy in the position determination. The tool executes the optimisation not only for nominal and ideal cases, but also for off-nominal configurations involving catastrophic or transient failures of the constellation satellites. The analysis of the GNSS robustness to failures changes considerably the number of satellites to be used per plane with respect to the original configuration designed in nominal conditions.
