Free-space laser communication system
Free-space laser communication systems use a laser beam as a carrier for the atmosphere and free space communication between two or more points, can be carried out deep space, synchronous orbit (GEO), medium-orbit (MEO), Low Earth Orbit (LEO) satellites, space experiments Station (SES) and between them and the Optical Ground Station (OGS) between the ultra high-speed communications, to achieve satellite - Space Experiment Station - on the ground, the complete three-dimensional high-speed communications networks.
Features
1, communications, large capacity space optical coupling using the latest WDM technology, communications capacity of 2.5Gbps;
2, communication distance with telephoto Cassegrain antenna structure and the new fiber-coupled transceiver technology to realize common transceiver antenna and ultra-narrow divergence angle of signal transmission to achieve long-distance communication;
3, mobile sites can be scheduled as needed quickly set up temporary communications system for emergency communications field. CCD,,; With built-in CCD surveillance and electric antenna pointing adjustment, semi-automatic target acquisition and alignment significantly reduce the system set up time;
4, anti-electromagnetic radiation interference laser communication system is mainly composed by a variety of optical devices, free from interference effects of electromagnetic radiation, which is militarily significant. ,; Communications laser beam divergence angle is very small, the optical communication link to nearby electromagnetic interference small;
5, confidentiality and strong because of the communication beam divergence angle is small, unable to communicate basic information on third-party interference, and listening.
