以卫星模拟器为基础,介绍了一种双星定位系统定姿的基本原理,解决了双星定位系统 存在的位置滞后即定位实时性较差的缺陷,把双星定位系统的位置与姿态信息和捷联惯导系 统的位置、姿态信息进行组合后,可有效地提高系统的精度.
Based on the satellite simulator, this paper introduces the basic principle of a dual-satellite positioning system, and solves the defect of the positioning lag of the dual-satellite positioning system that the positioning real-time performance is poor. The position and attitude information of the binary positioning system and the strapdown INS system position, attitude information combined, can effectively improve the accuracy of the system.
