摘要
针对单一导航导航系统在导航精度、稳定性、设备成本以及导航信息完备性等方面的局限性,设计了卫星导航/惯性导航组合导航系统;针对GPS导航系统受制于人及北斗导航系统发展尚不完善的特点,提出了基于北斗/GPS/SINS的军用机载组合导航系统软硬件设计;搭建了北斗/GPS/SINS组合导航系统硬件平台,采用基于不确定度的加权平均数据融合算法提高组合导航系统的导航可靠性和准确性;仿真结果表明,该组合导航系统稳定性好,可靠性高,定位准确。
Designed of the satellite navigation/Inertial Navigation Integrated Navigation System,owing to the navigation accuracy,stability,equipment costs and completeness of the navigation information and other aspects of limitations for a single Navigation system.Because of the kinds of GPS navigation systems controlled by others and the development of Beidou navigation system is not perfect,so proposed hardware and software design for military airborne Beidou/GPS/SINS integrated navigation system.Built Beidou/GPS/SINS integrated navigation system hardware platform,based on the weighted average data fusion algorithm uncertainty improve the reliability and accuracy of navigation integrated navigation system.The simulation results show that the integrated navigation system stability,high reliability,accurate positioning.
