摘要
针对双星定位系统(RDSS)存在的定位位置滞后的先天缺陷,根据组合导航定位系统输出速度误差小的特点,给出了一套消除RDSS位置滞后的方案,并对RDSS/SINS组合系统进行了建模。依据联邦滤波器理论,考虑到GPS的实际情况,提出了RDSS/Doppler/GPS/SINS多传感器组合导航系统的设想。仿真结果表明,该组合导航系统具有准确度高、自主性强的特点。
In order to eliminate the position lag for RDSS, a solution is proposed by taking the advantage of less output velocity errors of integrated navigation position system, and a model is built up for RDSS/SINS. Using the theory of federated filtering the RDSS/Doppler/GPS/SINS multi-sensor integrated navigation system is proposed for the first time by taking the actual case of GPS into consideration. Simulation results show that this system has high accuracy and good independence.
