望远镜系统误差动态修正的一种新方法
New method of dynamic correction for the system errors of telescope
摘要
系统误差的实时修正是保证望远镜观测精度最基本的条件之一.利用靶场试验数据进行计算机仿真,结果表明:与传统的单项误差法相比,球谐函数法对望远镜系统误差修正的精度在方位和俯仰方向上分别提高了30%和50%.并首次将该方法应用到了望远镜的系统误差动态修正中.
Abstract
The real-time correction of system errors is one of basic terms for guaranteeing the observation precision of telescope. Computer simulation is done by using shooting range test data. The conclusion is drawn that correction precision of spherical functions method is improved 30% and 50% than traditional monomial error method on azimuth and pitching in this paper. This method is firstly applied to dynamic correction for the system errors of telescope and the satisfied results have been obtained.
