摘要
水平角观测中,分组观测方向值后要进行联合测站平差。当观测组数或联测共同方向多于两个时,只能采用条件平差法,建立条件方程式后,解法方程得出各个方向值的改正数。采用MATLAB语言编制的测站平差程序,实现了读取数据、搜索共同方向、建立条件方程、解算改正数、首方向归0并同一和标准格式输出整个流程的自动化。
In horizontal angle observation,combined station adjustment proceeds after direction value group observation.When the number of groups of observation or the common directions of joint surveying is more than two,only conditional adjustment method can be used through setting up conditional equation and solving the correction number of each direction.The station adjustment program designed through MATLAB language realizes the whole workflow of automated data reading,common direction search,conditional equation set up,correction number solving,the first direction zero clearing and unification and standardized output.
