【摘要】：采用非差观测值构建误差方程,通过等价变换消除卫星钟差参数和接收机钟差参数,建立多个测站的联合等价双差观测方程。针对联合方程等价模糊度个数较多、相关性较强的特点,本文提出一种新的部分模糊度固定(PAR)方法。该方法将等价模糊度按照方差大小升序排列,通过循环剔除最大方差模糊度并进行Ratio检验,最终实现部分模糊度的固定。实例计算表明,相比完全模糊度固定(FAR)方法,PAR方法不仅具有更高的模糊度固定率和成功率,且提高了多基线精密定位的可用性,其坐标解算精度与FAR具有较好的一致性。
[Abstract]:In this paper, a new partial ambiguity fixed (PAR) method is proposed in this paper. In this paper, a new partial fuzzy degree fixed (PAR) method is proposed. The equivalence blur is arranged in ascending order according to the size of variance, and the maximum variance fuzziness is eliminated by cycle and Ratio test is carried out, and the partial ambiguity is fixed. The example calculation shows that the PAR method not only has higher fuzzy fixed rate and success rate, but also improves the precision positioning of multiple baselines compared with the complete fuzzy degree fixed (FAR) method. The accuracy of its coordinate solution is in good agreement with that of FAR.
