摘要
实现天文大地定位测量仪器的自动化观测,特别是消除传统天文大地测量人仪差影响的全自动测量,一直是我国天文大地测量工作者追求的目标。采用当今先进的恒星CCD成像技术、精密倾斜测量技术、计算机技术等研制而成的一种用于地面点精密天文定位的数字式测量设备,很好地解决了这一问题。本文论述了数字天顶摄影天文定位测量的基本原理,提出了数字天顶摄影天文定位测量仪器旋转轴方向天文坐标解算的技术途径。通过天顶摄影定位测量原理样机研制的工程实践,验证了该技术方法的可行性和正确性。
Automatic observing of instrument in astronomical geodetic surveying field, especially automatic observ-ing which can eliminate the effects of personal and instrumental equation in the traditional astronomical geodetic surveying, is the goal of the geodetic researcher’ s long term effort. Now this goal has realized, and the difficult problem has been solved by a ground-based precise astronomical positioning digital instrument, which is an inte-grated application of celestial CCD imaging technology, precise tilt measurement technology and computer technol-ogy. In this paper, the basic principle of the zenith digital camera astronomical positioning is introduced. A solution method of astronomical coordinates of the vertical rotation axis direction is proposed. With the experiments of the engineering prototypical instruments, the technology has validated.
