| In this paper, the optimization and application of GPS and traverse precise control network are studied according to the example of a railway line. According to the baseline data is prone to poor quality, GNSS closed loop transfinite problems, each combination of specific solutions,to achieve the corresponding qualified calculated;and the combination of "how to improve the precision of GPS control net precision small experiments, effects of GPS number on the precision accuracy of control network through the starting point distribution influence on GPS precision accuracy of control network and independent baseline closed loop are analyzed respectively, obtained a reliable conclusion,this provides a strong guarantee for the future of precision control network preliminary design of network and GPS network computing. |
