惯性/卫星组合导航系统不组合问题浅析

摘要

惯性导航系统与GPS/GLONASS（简称GNSS）组合导航系统在导航特性方面的互补性，使惯性/卫星组合导航系统获得了广泛的应用。但组合过程中出现的不组合问题对组合精度有着极大的影响。针对使用中出现的不组合问题，深入研究了组合机理，建立了相应的故障树，根据故障模式提出了常用排故策略，大幅提升了排故效率和能力。%Complementarities in the integrated navigation system in terms of navigation characteristics, make the INS/GPS Combined Navigation System more and more widely used . But the no combinatorial problems in the combination process wil bring great inlfuence on the combination accuracy. To solve the problem, research and analyze the mechanism, establish the corresponding fault tree and offer the common troubleshooting methods according to the fault mode , which wil greatly improve the efifciency and level of the troubleshooting.
