【摘要】 测地工作精度的高低直接影响着重力测量的精度,研究并采取行之有效的测地方法来配合重力测量工作是十分必要的。乌拉特后旗1:25万区域重力调查GPS测地工作采用1954年北京坐标系,重力测点平面位置、正常高采用差分GPS测量方法。结果表明,采用此方法既能满足技术要求,又达到了省时省力,且达到了重力测量的精度要求。更多还原

【Abstract】 The accuracy of geodetic work influences directly the accuracy of gravity survey.It is very necessary of researching and adopting practically geodetic method matching with effectively the gravity survey.The GPS geodetic work of 1:250,000 wulatehouqi regional gravity survey adopts 1954-beijing coordinate system.The plane position of gravity measuring point and normal height adopt difference GPS measurement method.The result expresses,adopting this method since can satisfy the technique request,come to saving time and labor,and come to the accuracy request of gravity survey.更多还原
