matlab编程完成一GPS网的平差计算。起算数据见文件“起算数据.TXT”；GPS网略图见“网图.jpg”；基线向量观测值和方差见“基线.bas”。根据已知起算数据和观测值建立数学模型并进行最小二乘平差计算和精度评定。代码和计算结果在实习报告中也已详细列出。-matlab program to complete a GPS network adjustment calculation. Initial data the document entitled " Initial Data. TXT"　 GPS network sketch map, see " Map. Jpg"　 baseline vector and the variance of observations, see the " baseline. Bas" . According to initial data and observations of known mathematical model and the least squares calculation and accuracy evaluation. Code and report the results in practice have also been detailed.
