摘要
本文叙述了APPLE-Ⅱ微机控制光电等高仪观测的系统。该系统可以实现自动导星、定位、跟踪与换星。在控制系统中应用了高精度的圆感应同步测角器和简单的恒星时钟卡。该系统的望远镜定位精度达±3″,跟踪精度达±5″。该套设备现在已投入正常使用,对改善观测条件和提高观测质量取得了明显效果。
This article describes the method of controlling the observation of a photoelectric ast-rolabe by an APPLE-Ⅱ computer. Changing, guiding and tracking for stars are all opera-ted by it. The stepping motor circular inductosyn and clock card of sidereal in the computer are used to control the telescope. The-pointing accuracy of the telescope is ±3'. The tracking accuracy is ±6'. This system has been used in regular observation.
