Analysis of the Kalman Filter with Different INS Error Models for GPS/INS Integration in Aerial Remote Sensing Applications
Direct Georeferencing Aerial Triangulation GPS/INS Integration
2015/12/17
In the Kalman filter used for the integration of GPS/INS, the inertial sensor error model is usually considered as a random constant or
random walk for both gyroscopes and accelerometers. However, th...

基于随机常数、随机游走和一阶马尔可夫过程组合的高阶IMU误差模型，建立了36阶卡尔曼滤波器，通过松散组合模式，最终实现了位置标准差±5cm、俯仰/横滚角标准差±0.002o、航向角标准差±0.008o的定位定向精度。
GPS/INS组合导航系统时间同步方法研究
导航 GPS/INS
2009/8/10
在设计和实现GPS/INS组合导航系统时,各子系统的时间同步是最关键的问题.首先对GPS/INS组合导航系统的时间同步问题作基本描述,然后在简要分析基于GPS接收机的1 pps脉冲信号同步采样技术的基础上,提出另外一种基于GPS和INS的1 pps脉冲信号的时间比对同步方法,这种方法能较好地解决GPS接收机由于失锁引起的1 pps信号抖动,将晶体振荡器的短期稳定度和GPS时间的长期稳定度结合起...
