| 摘 要： | 本文简要介绍了差分GPS/INS组合系统在单历元模式和多历元模式下适用的模糊度基本解算方法,分析了各自的优缺点,并提出了一种综合的GPS/INS组合系统模糊度处理策略。实验表明,在综合两种模式的动态模糊度解算方法的基础上引入基于周跳探测修复的模糊度传递以及INS辅助,对于不良观测条件下的模糊度固定具有十分显著的改善。 |

| Abstract: | This paper introduced the appropriate ambiguity resolution methods of the DGPS/INS integrated system in both single epoch mode and dual epoch mode.After analyzing their advantage and disadvantage,the paper put forward a synthetical method of ambiguity process in the integrated system.A sample showed that the ambiguity transfer based on the detection and repair of cycle-slip together with the INS damping could remarkably improve the ambiguity resolution especially in the bad observation condition. |
| Keywords: | GPS/INS ambiguity resolution matrix disassembling Dual Frequency Correlation method ambiguity transfer INS assistance |
