摘要
光学准直技术具有非接触、高精准度和高灵敏度的特点,在高精度方位传递和方位保存中已经被广泛应用。本文针对长征七号火箭射向测量工作的特点,详细介绍了两种基于准直技术的经纬仪对瞄十字丝测量法和外觇标测量方法,通过实际测量应用和获取的测量数据比较分析,表明这两种测量方法具有较好的应用性,可为航天发射任务提供可靠的数据参考。
Optical collimation technology has the characteristics of non-contact,high accuracy and high sensitivity,and has been widely used in high precision azimuth transmission and azimuth preservation.In this paper,according to the characteristics of the long March 7 rocket direction measurement,two theodolite alignment measurement methods and the external alignment measurement methods based on collimation technology were introduced in detail.Through practical measurement application and comparative analysis of the measured data,it was shown that the two methods had good application and could provide reliable data reference for space launch missions.
