摘　　要：惯性导航作为一种独立、便捷、稳定的导航方式,在众多对导航定位有特殊要求的领域正发挥着难以替代的作用。但惯性导航的误差会随时间逐渐积累,以至于出现较大偏差,直接影响了导航定位效果,因而在实际应用中是否能准确快速实时修正定位误差至关重要。针对目前普遍使用的轨迹匹配方法 ICCP算法,在数字化路网中惯导机动载体的路径匹配基础上对该算法的几个主要环节进行了改进。最后对照实验进行验证,实验表明,改进后算法的效率和精度有了显著提高。As a independent, convenient, and stable navigation method, the initial navigation is playing a irreplaceable role in many areas with special requests on positioning and navigation. However, the errors of initial navigation will increase with the distance accumulates and result in a large bias which affecting the navigation results directly. Thus, it is very important to correct the errors accurately and timely in the practical applications. The research targeted at the widely used route-matching algorithm—the ICCP algorithm, and made several improves in the main parts of ICCP algorithm based on the route-matching of initial navigation vehicles in road network. At last, a control-experiment was designed to test the improved ICCP algorithm. The results of the control-experiment show that the efficiency and accuracy of the improved ICCP algorithm has improved greatly.
