摘要
靶场大型机动站精密测量设备在站点安装时,通常不能做到设备的回转中心与站点地基环的大地测量中心点重合,这一偏差将影响设备对目标的测量精度,本文提出了一种能有效消除此偏差的方法。建立站点设备安装的回转中心定位公式,利用站点和方位标大地测量结果,经坐标变换重建设备回转中心的站址坐标和方位标数据,修正对中误差引起的设备对目标的测量精度影响。实际使用结果表明,此方法精度高、有效,且易于实施。
When a large-scale movable precision range measurement equipment is fixed, its rotation center is coincided hardly with the station pedestal mark which is positioned by geodetic survey, thus an aligning error is brought out, which will affect the measuring accuracy of target position. An effective method for e- liminating the error is proposed. Firstly, a position formula of an equipment rotation center is set up, then utilizing station pedestal mark and azimuth mark coordinates, the equipment rotation center of the station and the equipment azimuth mark positions can be achieved through coordinate transformations, so the aligning error is corrected. Practical results show that the method has high accuracy and effectiveness, and could be implemented simply.
