基于TCAR的三频非差模糊度快速解算方法

Quick Solution Method of Three Frequency Undifferenced Ambiguity by TCAR

目前,三频非差模糊度的求解是三频精密单点定位的一个重点问题,针对此问题本文提出了一种新的基于TCAR(Three-Carrier Ambiguity Resolution)的方法进行解算。TCAR的基本思路是对模糊度进行逐级固定,本文在原有基础上,在逐步解算的步骤中,根据每个步骤中的误差特性和想要实现的目的选择最优组合观测值,以此来实现快速解算三频非差模糊度的目的。经过实例验证可知,本文提出的方法能够提升模糊度的求解精度,可用于快速求解三频非差模糊度。

At present,The solution method of three frequency undifferenced ambiguity is a important question in the precise point positioning,for this question,a new method based on TCAR is proposed.Fixing ambiguity step by step is the basic idea of TCAR,this paper on the original basis and going to do it step by step.For the step of error characteristics and the purpose that we want to achieve,selecting the optimal combination of observations,to realize calculating three frequency undifferenced ambiguity fast.It is verified by an example,this method can promote the precision of ambiguity'results,it can used in the questions of realizing calculating three frequency undifferenced ambiguity fast.
