Embodiment Construction

[0111] figure 1 It is a schematic diagram of the implementation environment of the space communication system involved in the space communication method provided in some embodiments of this application. The implementation environment may include: at least two spacecraft 0 , each spacecraft 0 is provided with a communication system 01 of the spacecraft, and each communication system 01 of the spacecraft includes an APT subsystem 011 and a communication subsystem 012 .

[0112] The space vehicle 0 mentioned above may be a satellite, a spacecraft or a space station, or other devices operating in space. In space, since spacecraft usually rotate at a high speed, such as at a speed of 7 kilometers per second, the two spacecraft need to perform the acquisition process, alignment process, and tracking process first to ensure that the two high-speed rotating spacecraft are real-time alignment before a valid communication link can be established. Among them, the acquisition process in...

Abstract

The invention relates to a communication system of an APT subsystem and a spacecraft, and belongs to the technical field of space communication. The APT subsystem comprises a first controller, a firstterahertz transceiver and a terahertz antenna array which are connected in sequence, wherein the first terahertz transceiver is used for modulating and demodulating terahertz waves; the terahertz antenna array is used for transmitting and receiving terahertz waves; and the first controller is used for controlling the first terahertz transceiver to capture, align and track another APT subsystem through the terahertz antenna array. According to the invention, the capture, alignment and tracking efficiency of the APT subsystem is improved. The communication system is used for communication in space.

Description

technical field [0001] The present application relates to the technical field of space communication, in particular to an APT subsystem and a communication system of a space vehicle. Background technique [0002] With the development and application of space technology, especially orbital carrying and satellite communication technology, inter-satellite communication technology has become an important part of modern communication technology. [0003] The traditional inter-satellite communication system (also called inter-satellite link communication system, referred to as inter-satellite communication system) using inter-satellite (that is, between satellites) communication technology can include: Acquisition, Tracking and Pointing (Acquisition, Tracking and Pointing; APT) subsystem and communication subsystem. The communication subsystem is responsible for the transmission of inter-satellite information and is the main body of the inter-satellite communication system; the A...
