Document Type and Number:
WIPO Patent Application WO/2020/088511
Kind Code:
A1
Abstract:
The present invention relates to the technical field of outer space communications, and more particularly, relates to an acquisition, tracking and pointing (APT) subsystem and a communication system for a spacecraft. The APT subsystem comprises a first controller, a first terahertz transceiver and a terahertz antenna array connected in a sequential order. The first terahertz transceiver is used to perform modulation and demodulation of terahertz waves. The terahertz antenna array is used to transmit and receive terahertz waves. The first controller is used to control the first terahertz transceiver to perform, by means of the terahertz antenna array, acquisition, pointing and tracking operations with respect to another APT subsystem. The present invention enhances acquisition, pointing and tracking efficiency of an APT subsystem. The present invention is applicable to outer space communications.
