【摘要】 简要介绍了航天测量船测量设备方位取齐方法,分析了方位取齐的主要误差因素,提出了减小方位取齐误差的措施。就测量船现状而言,从大地测量成果的提供到标校结束期间船置平度的变化及经纬仪方位甲板零位的标定误差,是影响方位取齐精度的主要不可控因素。方位取齐误差的存在降低了测量船的姿态测量精度,其程度不仅与方位取齐误差有关,而且与船舶摇摆的幅度有关,这从另一角度说明了较好的海况对提高海上测量精度是有利的。更多还原

【Abstract】 The method of position consistence of the measuring equipment of Space Tracking,Telemetering and Command Ship is described briefly.The main error items are analysed.Also,some measures to lessen the influence of the error items to position consistence are discussed.To the present situation,the change in the leveling of the ship at dock during the calibrating and the precision of the position zero point of theodolite are main items,which impair the position consistence precision and are beyond control.The presence of position consistence error lowers the measuring precision to the ship carriage,which is related not only to the position consistence error,but also to the range of the ship rocked.This shows that a fine sea condition is good for improving the measuring precision of the equipment at sea.更多还原
