摘要
随着导航技术和控制理论的发展，组合导航系统已经成为当今最主要的导航系统。组合导航系统包括许多导航传感器，因此如何充分有效地处理来自多传感器的数据已成为组合导航系统的主要问题。在组合导航系统中，最先进的信息处理方法是联邦卡尔曼滤波。但联邦滤波器设计复杂，计算量大，很难满足一些高速巡航平台导航计算的高精度、高实时性要求。文章研究了巡航飞行器INS与GPS组合导航系统的卡尔曼滤波问题，设计了滤波器，并进行了仿真试验。
Integrated navigation system is the most important navigation system nowadays. Integrated navigation system consists of many sensors and how to efficient process data from all sensors become a mostly problem. In integrated navigation system federation Kalman filter is the most advanced method, but the federation Kalman filters construction is complex and the calculate estimate is great, so difficult to meet the high accuracy and real time request in high velocity fighting platform. The paper researches the Kalman filter in INS and GPS integrated navigation system using federation filter for reference and construct the state and measuring equation.
