摘要
随着我国北斗二代系统(COMPASS)的研发和建设,研究如何实现COMPASS与其他卫星导航系统的组合,特别是与GPS系统相组合具有重要的意义。此文首先介绍了COMPASS/GPS组合导航系统的组合应用,以提高定位的精度及稳定性;并通过48h观测数据,进行对比分析COMPASS导航系统、GPS导航系统和COMPASS/GPS组合导航系统三种模式下的定位精度,分析结果表明该组合定位系统的定位精度优于任何单一系统。
With the R & D and construction of Beidou second-generation system (COMPASS), China has the navigation system which is developed independently. Currently the Beidou navigation system is still under construction and can not fully meet the requirements of global positioning accuracy. The combination application of COMPASS/GPS system is beneficial to improve the accuracy and the stability of location. The COMPASS/GPS integrated navigation system is introduced firstly, then the contrastive analysis is made with the positioning accuracy of the Beidou navigation system, GPS navigation systems and Combination of the COMPASS/GPS integrated navigation system during 48 h observational data. The results show that the positioning accuracy of the combination positioning is better than any single system.
