基于水下GPS／INS／TRN组合导航信息融合技术研究

Information Fusion Based on Under-water GPS/INS/TRN

由于受到客观环境因素的影响，水下导航系统不可能像陆地导航系统那样，连续、不间断的定位，而必须依赖惯性导航技术。为了消除惯性导航系统随时间积累而产生的误差，我们采用了基于Gps／INs／TRN信息融合技术的水下组合导航系统方案，并进行了初步讨论。通过信息融合有效地提高了导航系统的精度和可靠性。

For effect of objective environment factor, under-water navigation system cant position continuously, it must depend on inertial navigation technology. In order to removed inertial navigation system error with time accumulation, we made the design of under-water integrated navigation system based on GPS/INS/TRN information fusion technology and discussed primarily. The design improved accuracy and reliability of navigation system by information fusion.
