航天测量船是一座海上活动测控站,在辽阔的海洋上对导弹、航天器进行跟踪、测量和控制。航天测量船在海上工作状态下,随着航速、航向的变化,以及海浪冲击、温度变化等影响,会产生不可忽视的弹性变形。这种变形会带来航天测量船的测量误差,特别是雷达和光电经纬仪等测控设备相对船体基准的动态变形,如果不能测量并修正,这些设备就无法完成高精度测量的任务。
Aerospace survey ship is a marine observation and control station, in the vast ocean on the missile, spacecraft tracking, measurement and control. Spacecraft in the sea working conditions, with the speed, heading changes, as well as the impact of waves, temperature changes, will have to produce elastic deformation can not be ignored. Such deformation will bring errors in the measurement of the spacecraft, especially the dynamic deformation of the measurement and control equipment such as the radar and theodolite that are relative to the hull reference. If they can not be measured and corrected, these devices can not accomplish the task of high-precision measurement.
