摘　　要：通过对自由测站方法和传统外业观测方法的比较,阐述自由测站方法的优势。对多余观测数进行对比、分析,证明在一定条件下,自由测站方法可代替传统外业观测方法进行平面控制网测量。通过实例分析,验证当控制点位置已固定时,自由测站方法可对原网形进行优化,从而提高控制网的精度和可靠性。By comparing free station with traditional observation in field work, it shows the advantages of free station. By comparing and analyzing the excess observations, it proves that in certain condition, horizontal control net measurement can be realized by free station instead of traditional method. The case study indicates that when control points are fixed, free station can optimize the original net form so that it is able to improve the accuracy and reliability of the control net.
