Matlab软件支持下的GPS基线向量网三维约束平差

The Tri-Dimentional Constrainted Adjustment for GPS Baselines Vector Network Based on MATLAB Software Platform

本文在对GPS基线向量网三维约束平差的数学模型进行详细引述及推导的基础上,结合某实际工程案例,利用Matlab强大的矩阵计算功能对基线向量网的三维约束平差进行了计算,解算结果与中海达HDS2003版商用软件相比较结果一致。本文可以为GPS数据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与帮助。

Nowdays,most GPS data processing personnel using commercial GPS software or sophisticated scientific software for baseline vector solution in control network. However because of surveying and mapping techieians＇ inadequate grasp about the mathematical model and underlying technologies in GPS software, there are some obstacles in high accuracy re- quirements of certain applications using GPS technology. After the three-dimensional mathe- matical models for baseline vector network is quoted and derived in detail, this thesis com- bined with a practical engineering cases and in the use of Matlab powerful matrix calculation function carried out 3D constrained adjustment calculations for GPS baseline vector network. Solver results obtained through Matlab compared to those obtained by HDS2003 commercial software are consistant. This paper provide a reference and help for GPS data processors and related professional college students having a better understanding and mastery for GPS net- work adjustment.
