星基增强系统(SBAS)用户端定位算法设计

Design on Satellite Based Augmentation System Client Positioning Algorithm

星基增强系统作为GNSS的重要组成部分,通过提供广播星历差分改正与完好性增强信息,满足高精度高完好性用户使用需求。本文主要设计了一套完整的星基增强系统单双频用户端定位算法处理策略,根据自编程序,验证了算法的正确性。

Satellite Based Augmentation System(SBAS)plays an important role in GNSS which can meet the needs of users with high precision membrane brightness by providing broadcast Ephemeris differential correction and integrity enhancement information.A complete set of SBAS single and dual frequency client positioning algorithm processing strategy is designed in the paper.According to the self-programmed program,the accuracy of single and dual frequency single-point positioning and enhanced positioning is verified.
