摘要
组合导航系统是现代导航设备的一个主要发展方向,在人类航空、航天等领域被广泛运用。实现高精度、高可靠性、高抗干扰性是任何一种单一的导航系统都难以胜任的。组合导航系统通常以SINS为主导航系统,将GPS等导航定位误差不随时间积累的导航系统作为辅助导航系统,应用传感器信息融合技术和滤波技术,对组合系统的状态变量进行估计,从而给出高精度的导航参数。
the integrated navigation system is one of the main development direction of modern navigation equipment, was widely used in human aerospace and aviation, etc.To realize high precision, high reliability and high anti-jamming is every single navigation system is difficult to do.Integrated navigation system is given priority to with SINS navigation system normally, such as GPS navigation positioning error does not accumulate over time of the navigation system as the auxiliary navigation system, the application of sensor information fusion technology and filtering technology, the combination of system state variables are estimated, which gives a high precision navigation parameters.
