摘要

摘要: 针对基于GPS下似单差模型不能解算大变形量的问题,文章充分利用北斗卫星导航系统（BDS）全星座播发三频信号的优势,采用BDS三频组合观测值模糊度快速解算方法快速解算模糊度,实现似单差模型下BDS单历元快速提取大变形信息,并比较了BDS和GPS下似单差模型的解算精度．高精度三维移动变形测试平台实验表明,采用上述方法,BDS似单差模型可快速解算大变形量,且BDS和GPS系统下似单差模型的解算精度相当,可达到厘米级.

Abstract: Aiming at the problem that the GPS similar-single-difference model cannot extract the large deformation information, this paper takes full advantage of the three-frequency signal broadcasted by the BeiDou full constellation, A method for quick extraction of deformation information with triple-frequency combination ambiguity resolution and similar-single-difference model based on BDS was studied. Experiments on the high-precision three-dimensional mobile testing platform show that the above method can quickly extract large deformation information. its accuracy is equivalent to that of GPS and can reach centimeter level.
