| 摘 要： | 针对传统的双差分载波相位实时定位平台精度低的特点,本文设计了一种新型的基于单周期多基线组合的实时定位平台。该平台采用单周期整周模糊度算法进行模糊度解算,有效避免了周跳和初始化问题,并组合多基线测量观测值,有效地减少了单基线长度增加带来的影响,通过对平台进行建模仿真,表明其与传统平台相比具有更好的稳定性和精度。最后,本文将GPS多基线测姿算法引入,将该平台应用到空中对准技术中,进行对准仿真,取得了更高的速度和精度。

| Abstract: | A new positioning platform based on single-epoch multiple-baselines linear combination is developed for the low accuracy of the traditional double-difference carrier-phase positioning platform.In this platform the single-epoch integer ambiguity resolution is used to eliminate the cycle-slip detection and initialization problem.Combined with the multiple-baselines observed values,this platform also effectively decreases the effect,induced due to the increasing length of the single baseline.It shows more robu... |
