摘要
本研究通过在池州学院内布设GNSS控制网,并对所有网点进行水准联测,获取GNSS大地高和水准高,结合测区点位分布的实际情况,基于拟合点位置分布制定几组不同的方案进行实验,在此基础上分别采用最小二乘法、整体最小二乘法对GNSS高程进行拟合,得出了许多有益的经验与结论,以期为今后似大地水准面精化以及其精度评定的方案选择提供理论基础。
Taking the small area of Chizhou University as the research object,the GNSS control network is set up in the school,and the leveling of all points is measured to obtain the GNSS geodetic height and leveling height.Combined with the actual situation of the location distribution of survey points,several groups of different schemes based on the distribution of fitting points.On this basis,the least squares(LS)and the total least squares(TLS)methods are used to fit the GNSS elevation,and many useful experiences and conclusions are obtained,which provide a theoretical basis for the future quasi-geoid refinement and its accuracy evaluation scheme selection.
