摘　　要：利用二维水平基准传感器与测角装置联合测量信息 ,替代自然水天线与人工读数 ;利用CCD面阵辅助精确瞄准 ;测量瞄准线与水平面之间的天体高度角 ,再依据两星或三星等多天体定位原理进行天文定位导航 ;研制出一种新型的自带人工水平基准的手持数字式天文定位装置系统。本文对该系统的结构组成与测量原理、误差分析。A new type of portable digital astronomical instrument for measuring ship's position with man made water level datum is developed. In this instrument two dimensional water level datum sensor is combined with angle measuring device to get information instead of natural water level and artificial readings, a CCD component is applied to aim accurately and to measure the altitude angle of celestial body between aiming line and water level plane. Then astronomical positioning navigation can be carried out in accordance with the multi celestial positioning principle of two or three stars. In this paper the complete description of the configuration, measuring principle error analysis, correction principle and method etc. of this instrument is given.
