DIRECTIVITY CONTROLLER OF ANTENNA FOR INTER-SPACECRAFT COMMUNICATION

摘要

PROBLEM TO BE SOLVED: To obtain a directivity controller of an antenna for communication between spacecraft which makes an antenna accurately direct in the direction of the spacecraft of the other party even after executing orbit control and realizes reliable data communication when 1st spacecraft navigating while executing orbit control performs data communication through 2nd spacecraft. SOLUTION: This controller calculates a orientation command value based on orbit data 26 corresponding to the orbit control of 1st spacecraft and executes the control of drive of an antenna in the direction of 2nd spacecraft by providing an accelerometer 23 that detects acceleration generated by the orbit control of the 1st spacecraft and an acceleration integrating part 25 which outputs the orbit data 26 of the 1st spacecraft from the acceleration.
