ON-BOARD LASER COMMUNICATION TERMINAL Russian patent published in 2025 - IPC H04B10/118 H04B7/185 

FIELD: communication technique.

SUBSTANCE: present invention relates to communication, particularly to an on-board laser communication terminal. Disclosed is an on-board laser communication terminal, comprising: optical bidirectional lens system with a dynamically controlled active optical element for correcting the direction of radiation beams, comprising two spectrally spaced apart channels with an optical axis automatic adjustment system using a triple prism, a tracking sensor and using a micro-electromechanical mirror element to control the radiation direction to guide and maintain the direction of the information channel from a small spacecraft (SSC) to a ground optical station (GS) and made with possibility to perform radiation pattern formation of optical information channel from SSC to GS along downlink and from GS to SSC along uplink; optical beacon system intended for GS accurate guidance to SSC; photodetector path configured to detect an optical information channel between the SSC and the GS along the uplink; laser sources with control boards, designed to generate and modulate monochromatic radiation of the required energy for the information channel and for the channel of the guidance system; PLD board configured to control the on-board terminal devices on the SSC, including for the channel information sequences generation and decoding between the SSC and the GS; and adapter boards for powering, connecting and converting interfaces of devices inside an on-board terminal with PLD.

EFFECT: wider range of technical means of solutions for such purpose.
