摘要
针对单一导航系统的性能不能满足全天候、全天时、高精度、高可靠性的舰船导航信息测量要求,提出了一种基于多传感器信息融合(MSF,Multi-SensorFusion)的容错组合导航系统方案;方案中增加了子滤波器故障隔离检测模块,对系统状态进行全参量最优估计和容错处理;对融合后的系统精度和故障隔离能力进行了试验仿真验证,结果表明所设计方案能够提高系统的精度和可靠性。
In view of the performance of a single navigation system is unable to satisfy the requirements for measuring navigation informa- tion of the ships of all--weather, all--time, high--precision and high reliability, a solution of a fault--tolerant integrated navigation system based on Multi--Sensor Fusion （MSF） is proposed in this paper. The solution, which has an additional sub--filter fault detection module, makes optimal estimate and fault--tolerant treatment to all parameters of the system status. Afterwards, an experimental simulation valida- tion is done to the precision and fault isolation ability of the fused system and the results show that the accuracy and reliability of the system are improved by the designed solution.
