摘　　要：鉴于传统的位移监测实验模式存在诸多弊端,本文设计了一种基于北斗的高精度位移监测创新试验平台。首先,建立北斗单历元定位数学模型,给出一种适用于北斗多频信号主辅频相关法(MAXCOM)的整周模糊度快速解算流程;然后,基于Visual Studio 2019开发平台,运用C#编程语言,研制一种北斗高精度位移监测创新试验平台(LSMS)。试验测试与分析结果表明,LSMS试验平台的北斗位移监测精度可达厘米级,其中北向精度优于0.9 cm,东向精度优于1.2 cm,垂直精度优于3.0 cm,水平精度优于1.5 cm,点位精度优于3.3 cm。本文方法及试验平台用于北斗高精度位移监测创新试验是行之有效的。In view of the disadvantages of the traditional displacement monitoring experimental mode,the BDS-based high-precision displacement monitoring innovation experimental is designed.Firstly,the mathematics model of BDS single epoch positioning is built,and the flowchart of fast integer ambiguity resolution applicable to the main and auxiliary correlation method(MAXCOM)of BDS multi-frequency signals is given.And then,the BDS-based high-precision displacement monitoring innovation experimental platform(LSMS)is developed based on Visual Studio 2019 development platform using C#programming language.The experimental testing and analysis results show that the BDS-based displacement monitoring accuracy of LSMS experimental platform can reach cm-level,and the monitoring accuracy is better than 0.9 cm in the north-direction,1.2 cm in the east-direction,3.0 cm in the vertical-direction,1.5 cm in horizontal-direction and 3.3 cm in point-positioning for the observation epochs.The proposed method and experimental platform in this paper is feasible and effective applied for BDS-based high-precision displacement monitoring innovation experimental.
