The author first explains that large - scale measurement device is one of the most basic measuring methods of obtaining external trajectory data and flight status . lt is pointed out that the accurateness of the main - item axis system deviation correction ( including vertical , level and collimating axis deviation ) of large - scale measurement device error is of critical importance to the precison of measuring device ' s surveying angles . to improve its precison , the influence of axis system deviation on surveying angles must be corrected 首先说明了在现代航天靶场中,大型测量设备是获取外弹道数据和飞行状态的最基本的测量手段之一,指出大型测量设备测量系统误差的主项轴系偏差(包括垂直轴偏差、水平轴偏差和照准轴偏差)改正的精确与否直接关系到测量设备的测角精度,因此要提高测量设备的测角精度,必须对轴系偏差对测量角的影响进行改正。
