Real-time position calculation method for large-diameter radio telescope panel using angle sensor

With diameter enlarging and frequency upgrading of the radio telescope, the telescope structure is more complex, and the telescope efficiency and steering are more and more sensitive to structural distortion. It is difficult if we adopt traditional compensation method to satisfy the telescope electrical performance requirements, So taking the initiative to adjust the main reflector telescope to compensate telescope performance is essential, but the common active surface adjustment technology does not well meet the important instantaneity index. To this end, this paper proposes a real-time position calculation method for large- Diameter radio telescope panel using the angle sensor. The physical position and attitude of the telescope panel can be computed quickly through using the reading of the angle sensors,Which can make the active adjustment of the telescope panel more efficient and the telescope electrical performance being better.
