摘要:
摘要:基于北斗星座的双频基线解算和模糊度固定方法研究,可实现中长基线的快速精密相对定位,提高GNSS在障碍环境下的应用能力。文章对17.2至55.8 km长度的4条基线的GNSS多星座实测数据进行了基线解算,从各基线观测数据中分别提取不同时段长度的观测数据,对比分析了基于单COMPASS星座、单GPS星座以及GPS/COMPASS组合星座的基线解算结果。结果表明:在基线观测时段长度达到60 min及以上的情况下,基于单COMPASS星座的基线解算结果与单GPS系统解算的结果相比没有显著的差别,基线北/东/高分量的偏差大部分都小于2 cm,而在观测时段长度小于30 min的情况下,单COMPASS系统的基线解算精度低于GPS系统,基线北/东/高分量偏差达到分米级;在高卫星高度角条件(>30°)下,单COMPASS系统解算的基线精度较单GPS系统低。
Abstract:
Abstract: China’s BeiDou satellite navigation system (COMPASS) is developing rapidly, which provides favorable conditions for precise relative positioning based on COMPASS constellation. In order to achieve rapid precise relative positioning for medium-long baselines and improve GNSS application ability in obstacle environment, methods of dual-frequency baseline resolution and ambiguity fix are discussed for COMPASS system, and real multi-constellation GNSS observation data for 4 baselines with distance varying from 17.2km to 55.8km collected are processed based on COMPASS, GPS and COMPASS+GPS combined system. Baseline results based on single system and combined systems are analyzed and compared using different observation periods. Also the baselines are processed and analyzed under different satellite cut-off elevation angles, ranging from 15° to 50° respectively. Calculation results show that: in the case of long observation periods (>60min), the biases in N/E/H component of the baselines are most within ±2cm using only COMPASS observation data. There is no obvious difference between the baseline results based on COMPASS and the baseline results based on GPS. While in the case of very short observation period (<30min), the biases in N/E/H component of the baselines reach decimeter level based on COMPASS. And in the case of high cut-off elevation angles (>30°), the performance of baseline resolution using only COMPASS is inferior to that of GPS, especially for medium-long distances. The precision of baseline results is obviously improved based on COMPASS+GPS combined system compared with single system with very short observation period or high cut-off elevation angle.
