| 摘 要： | 文中研究了ICCP算法的基本原理,分析了ICCP算法的特点,针对ICCP实时性差的不足,借鉴计算机编程思想中的移位寄存器原理给出了改进ICCP算法,同时,改进ICCP算法中每个采样点都可以有多个匹配结果,通过对这些匹配结果求加权平均可以有效消弱结果中的随机误差,从而提高了匹配的可靠性。并通过一个仿真实例,表明改进ICCP算法可以有效改善ICCP算法的实时性,经度方向精度与ICCP算法相当,纬度方向精度有明显的提高。 |
| 关 键 词： | 改进ICCP算法 重力匹配辅助导航 移位寄存器 刚性变换 |

| Abstract: | In this paper,the principle of ICCP algorithm was researched,and its characteristic was analyzed,referring to the idea of shift register,improved ICCP algorithm was advanced,which aims at the insufficiency of ICCP in real-time,simultaneity,the improved ICCP algorithm received many matching results for every sampling,and calculating weighted average to these matching as the last result could lower the stochastic error,which improved its reliability.Last,one actual application was presented,the results indicated that the improved ICCP could improve ICCP on real-time,the precision of improved ICCP in longitude corresponded to the ICCP,a marked improved in latitude. |
| Keywords: | improve ICCP algorithm gravity matching aided navigation shift register rigidity transform |
