载波相位差分GPS/惯性组合导航

载波相位测量是目前测量精度最高的测量方法，所以载波相位差分ＧＰＳ同惯导组合能获得高精度的导航系统。但载波相位测量需要确定整周模糊度，现在已探索出多种算整周模糊度的方法，但这些方法而且需要一定的解算时间。文中提出了把模糊度作为状态变量进行组合的方法，用整周模糊度的浮点解同样可得到较高精度的导航系统。仿真结果表明，该方法是行之有效的，扩大了组合系统的应用范围，对航空、航天、铁路、航海等载体的高精度导航

Carrier Phase Differential GPS/INS Navigation System

Carrier phase measurement is a measuring method of the highest precision at present. So, GPS carrier phase measurement integrated with INS can get high precision navigation system. However, It is necessary to know ambiguities in carrier phase measurement. Now, Some methods to resolute ambiguities are put forward, but most of them are complex and need quite time to do that. Ambiguities are regarded as state variables and taken part in the integration. A high precision navigation system is obtained without decideded ambiguities. The results show that this method is efficient, enlarge the application field of integration system. It is valuable for aeronautics, astronautics, railway and voyage.
