摘要
随着卫星导航产业的飞速发展,对于定位解算的精度和速度要求也不断提高,为了满足现代高精度、快速性定位的要求,提出一种新型软件接收机定位解算方法,该方法对伪距方程组中的公共白噪声和时钟误差进行消除,然后再进行迭代计算,最后采用位置差分的方法对迭代结果进行差分运算得到定位结果。计算机实验仿真,结果表明,与传统的最小二乘法相比,该方法具有更高的定位精度以及更快的迭代速度,对于软件接收机定位解算的研究具有重要的意义。
With the rapid development of satellite navigation industry, the requirement of positioning calculation＇s precision and speed are also continuously improving, In order to meet the need of modern high precision and fast positioning＇s requirement, a new localization method of software receiver is proposed. The method eliminates the white noise and the public pseudo-range error before the iterative computation, Which can enhance the positioning accuracy and speed up the localization speed of iteration, and then, it improves the precision of localization by using of position differential method again. The computer simulation experiments results indicate that this method has higher accuracy and faster speed of iteration when compared with the traditional least square method. It is of important significances to the research about positioning calculation of software receiver.
