Abstract

The present invention discloses an inter-satellite link antenna scanning acquisition device and method. The device comprises: an orbit prediction module configured to predicate antenna parameters; a scanning parameter setting module configured to obtain scanning parameters; a maximum capture time calculation module configured to obtain the required time of scanning the whole determinate region according to the antenna parameters when two satellite antennas are rotated at opposite directions; a timer module configured to limit the scanning time of the two satellite antennas being rotated; a first scanning strategy module configured to perform scanning of the rotation of the two satellite antennas at the opposite directions and determine whether the acquisition is successful or not; and a second scanning strategy module configured to allow the two satellite antennas to return back to the direction of the opposite antenna through orbit prediction at a constant linear velocity and perform scanning in a mode of only one satellite antenna rotation when the two satellite antennas cannot be subjected to successful acquisition in a maximum acquisition time, and determine whether the acquisition can be successful or not. The device can effectively reduce the acquisition time and improve the probability of successful acquisition in a short time.

Description

technical field [0001] The present invention relates to the technical field of inter-satellite link ATP (Acquisition Tracking and Pointing, acquisition tracking and aiming), in particular to an inter-satellite link antenna scanning acquisition device and method. Background technique [0002] The inter-satellite link ATP technology is used when two satellites need to establish an inter-satellite link for communication to achieve rapid and precise alignment of their antennas. The process of precise alignment is mainly divided into three stages: acquisition, tracking and aiming. The first stage of antenna capture refers to the transmission of signals at one end of the communication link, and the satellite antenna at the other end points to the satellite position of the other party in the orbit forecast. Since there is a certain error in the antenna pointing, it is necessary to search in the area near this position, and finally successfully capture the other party. Satellite sig...
