BDS/GP S/GLONASS组合单历元姿态测量性能对比分析
Comparison and Analysis of Single-Epoch Attitude Measurement Performance with Combined BDS/GPS/GLONASS
摘要
Abstract
Compared with a single satellite navigation system, the combination of multi-GNSS can significantly in-creases the number of available satellites, and improves the satellite geometry, so the application of combination of multi-GNSS becomes the focus of attention in recent years. The carrier attitude determination with combined BDS/GPS/GLONASS has the unmatchable advantage over a single system in complex observing conditions. This paper describes the double difference model used by ultra-short baseline solution with combined BDS/GPS/GLONASS and the basic principles of attitude determination, then the single-epoch attitude determination performance of multi-frequency combined BDS/GPS/GLONASS is analyzed. By setting different satellite elevation mask angle in static data analysis, it shows that: Compared with a single system or a combination of the two systems, the attitude determination with combined BDS/GPS/GLONASS can effectively improves the accuracy, stability, and availabili-ty. The attitude determination with combined BDS/GPS/GLONASS shows more value when carriers are moving in tall buildings, canyons and other shadowed serious complex environments.关键词
