Abstract

There are seven valid satellites in Beidou navigation system (COMPASS) now, including three Geostationary Orbit satellites (GEO) and four inclined Geo-synchronization orbit satellites (IGSO). In this paper, assessment methods of COMPASS satellite pseudorange observation’s accuracy are researched into and COMPASS data are analyzed with self-compiled software in detail. Code pseudorange point positioning accuracy was also analyzed with the software and COMPASS data collected from September 5 to 11, 2011, and data quality control methods are studied during this period. The results demonstrate that: COMPASS pseudorange’s multi-path effects and measurement errors are about 0.5–3 m; The percentage of coordinate differences—|ΔN|, |ΔE|, |ΔU| within less than 10 m in pseudorange single point positioning (October 2) are 67, 100 and 64%, respectively; the accuracy (RMS) in the North, East and Up direction during these 7 days are about 9.70, 5.56, 11.25 m; The horizontal and three-dimensional positioning accuracies are about 11.23 and 15.92 m respectively.
