GPSExample of control network adjustment

Data file format description:
GPSThere is only one data at the beginning of the network data file, that is, the prior unit weight mean square error,The unit is cm. Not less than 5 consecutive lines“=”Is separated by an equal sign separator, followed by a known point. Mark a line of equal sign separator, followed by vector group arrangement.
Vector groups are also separated by an equal sign separator. The baseline vector in each vector group and its variance covariance matrix shall have at least 5 consecutive lines“-”The minus separator separates.
Data is separated by commas or tabs or spaces or semicolons. The first character of the roll call must be a letter or a number.

GPS控制网平差范例

数据文件格式说明:
GPS控制网平差软件 》数据文件的开始一行只有一个数据,即先验单位权中误差,单位为cm。后跟一行不少于5个连续“=”的等号分隔符分隔,接着为已知点。打一行等号分隔符,后面是向量组排列。
向量组之间也用等号分隔符分隔。各向量组内的基线向量与其方差协方差矩阵之间用一行不少于5个连续“-”减号分隔符分隔。
数据之间用逗号或制表符或空格或分号分隔。点名的第一个字符必须是字母或数字。
