Abstract

In this paper we study the problem of how to determine the coordinates of a point a telescope is directed to on the basis of data obtained from a 9DOF sensor board. On the 9DOF sensor board there are three sensors: the gyroscope, accelerometer and magnetometer. By combining the data from all the three sensors one obtains the Eulerian angles in the system tied to the sensor board. The Eulerian angles are transformed into the horizontal and equatorial coordinates in order to obtain the point the telescope is directed to.

基于惯性测量单元的望远镜指向

在本文中，我们研究了如何根据从9DOF传感器板获得的数据来确定望远镜指向的点的坐标的问题。在9DOF传感器板上有三个传感器：陀螺仪、加速度计和磁力计。通过组合来自所有三个传感器的数据，可以获得与传感器板相连的系统中的欧拉角。将欧拉角转换为水平坐标和赤道坐标，以获得望远镜指向的点。[塞尔维亚教育、科学和技术发展部项目，2011－2016年拨款号TR32043，拨款号176011：天体和系统的动力学和运动学]
