【摘要】 在GPS控制测量中,若未知地方独立坐标系的相关定义参数时,便不能进行约束平差而只能用坐标转换的方法来求取未知点的地方坐标,在TGO系统中用点校正来解决问题。基于此,对点校正问题进行了理论和实例分析,结合笔者应用TGO的经验,得出了一些在工程测量中有益的结论和建议。更多还原

【Abstract】 In GPS control survey,as if relevant definition parameter of local independent coordination system were unknown,the constraint adjustment couldn′t adjust,and that can do nothing but can apply coordinate translation method to solve the local coordinate of unknown points;in TGO system,the point calibration is used to solve this problem.This paper analyzed the point calibration problem in theory and the example;combing with authors own experience,authors get some of beneficial conclusions and proposals in engineering survey.更多还原
