Method of measuring rotating speed of sphere using accelerometer |
| abstract |
The present invention relates to a method of measuring the rotating speed of a sphere for controlling the posture of a satellite. The method includes: an accelerometer installing operation in which a pair of accelerometers is installed at each accelerometer coordinate axis, the accelerometers being located in the sphere; an accelerometer coordinate axis alignment operation in which the accelerometer coordinate axes are aligned to allow the accelerometer coordinate axes to be in line with system coordinate axes, respectively; an acceleration measuring operation in which a current is applied to an electromagnet to rotate the sphere and sequentially measure the acceleration; an acceleration calculating operation in which only the acceleration generated by the rotation of the sphere is calculated; and a rotating speed calculating operation in which the rotating speed of the sphere with respect to each coordinate axis is calculated using the acceleration. |
