Title:
AUTOMATIC SATELLITE CATCHING DEVICE
Document Type and Number:
Japanese Patent JPH0231213
Kind Code:
A
Abstract:
PURPOSE:To automatically control the docking or the rendezvous to a target satellite by using a radar equipment to catch the satellite in a long distance and plural cameras to catch the satellite in a short distance respectively. CONSTITUTION:A radar device (h) catches a target satellite (a) in a long distance. While plural cameras (b) are driven by the motors (d) and the motor drivers (e) when the satellite (a) gets close to a satellite catching device so that the satellite (a) can be caught by the cameras. Then the encoders (c) acquire the relative positions, the optical axes, etc., of those cameras. Thus the 3-dimensional coordinates are identified and the attitude information on the satellite (a) is obtained. The visual information obtained by the cameras (b) are converted into the digital signals by a converting device (i) and sent to an arithmetic unit (f). The unit (f) compares the information on the satellite (a) stored in a memory (g) with the visual information obtained by the cameras and sends the due information to an attitude controller.
