Study on Multi- Sensor Combined Navigation System
Author(s): 
Pages: 67-72
Year: Issue:  2
Journal: AEROSPACE CONTROL

Keyword:  惯性导航全球定位系统组合式导航卡尔曼滤波;
Abstract: 设计了一种由INS、GPS和Doppler测速雷达构成的多传感器组合导航系统.采用GPS伪距、伪距率以及Doppler速度与INS组合,建立了其卡尔曼滤波方程,设计了飞行轨迹,给出了惯性元件精度较低时组合系统的仿真输出.仿真结果表明,多传感器组合导航系统能有效提高导航精度,降低对惯性元件的性能要求,是导航系统的发展方向.
