GPS/GLONASS组合精密单点定位性能分析
PERFOMANCE ASSESSMENT OF GPS/GLONASS PRECISE POINT POSITIONING
摘要
Abstract
After explaining the method and models for Precise Point Positioning ( PPP) based on combined GPS and GLONASS, the positioning accuracy of static and kinematic PPP and convergence of kinematic PPP for GPS, GLONASS and their combination were compared with each other by using the data processing software developed by the author. The PPP of numerical results show that: GPS, GLONASS and their combination have access to centimeter-level static and kinematic positioning accuracy, but the last is better than the former two in statistical accuracy and the GPS/GLONASS combination can improve the convergence speed of kinematic PPP, particularly prominent for the case of less observed GPS satellite.关键词
