MATLAB软件支持下的GPS基线向量网的三维无约束平差

The 3D Unconstrained Adjustment for GPS Baselines Vector Network Based on MATLAB Software Platform

在采用GPS后处理软件进行基线解算且经过各项检核合格之后,需要进行基线向量网的三维无约束平差、三维约束平差、二维约束平差等处理过程。而目前相关的文献中对采用秩亏自由网平差进行GPS基线向量的无约束平差涉及较少,且往往是一笔带过[1]。本论文在对GPS基线向量网三维无约束平差及秩亏自由网平差数学模型进行引述的基础上,结合某工程案例,利用MATLAB强大的矩阵计算功能进行了基线向量网的三维无约束平差。以期为GPS数据后处理人员以及相关专业的大中专在校学生对该内容的理解与掌握提供一定的借鉴和帮助。

When theGPS baseline solutions in the use of GPS postprocessing software have been completed and qualified by the check, surveyors have to process 3D constraint adjustment, 2D constraint adjustment etc. Related literatures involved unconstrained adjustment of GPS baseline vector on Rank Defect Free Network Adjustment described in less. This thesis combined the case of a project use MATLAB powerful matrix calculations of the baseline vectors＇ 3D unconstrained ad justment based on quoted in the mathematical model of 3D unconstrained adjustment of GPS baseline vector and the rank defect free network adjustment. So that GPS data processors and related professional college students have a better under standing and mastery.
