摘　　要：针对某一类测量仪器自身配套设备已经固化的情况下,为了提高天文定向测量精度,应在不同时间段及不同地理纬度选择合适的目标天体。文中通过对天文定向测量模型进行详细深入的分析研究,总结出误差方程,得出时间和地理纬度对天文定向测量结果的影响因子。以自研的天文定向测量仪器为依托,针对不同的观测天体在不同时间段和不同的地理纬度,对其误差因子进行数据分析,最后得到白天以太阳为观测目标时,观测时间段的选择方法,以及夜晚以北极星或其他天体为观测目标时的选择方法,进而从观测源头提高测量精度。For the case of a certain type of measuring instrument has its own equipment cured,in order to improve the accuracy of astronomical orientation measurement,suitable celestial target should be selected in different time periods and different geographic latitudes.In this paper,through a detailed and in-depth analysis of the astronomical orientation measurement mathematical model,summed up the error equation,and obtained the influence factors of time and geographic latitude on the astronomical orientation measurement result.Then relying on the self-developed astronomical orientation measurement instrument,analyzed the error factors of different observing celestial bodies in different time periods and different geographic latitudes.Finally obtained when the sun as the observation target,the method for selecting the day observation period,and the selection method of observing celestial bodies when the North Star or other celestial bodies are the target at night,further improve the measurement accuracy from the observation source.
