Multi mission capable optical inter satellite link
Free-Space Laser Communications XXXIII, 2021General Atomics Electromagnetics (GA-EMS) has developed a free space optical laser communication terminal (LCT) for space applications. The system operates at 1550 nm and utilizes on-off keying to support a data rate of up to 5 Gbps. The system has undergone assembly, integration, and testing and is being integrated into the host spacecraft in ...

Homodyne BPSK Based Optical Inter-Satellite Communication Links
24th AIAA International Communications Satellite Systems Conference, 2006Summer 2007, Tesat will verify laser communication terminals based on homodyne BPSK (binary phase shift keying) in-orbit. A 5.625 Gbps LEO-LEO laser communication link, established between the German satellite TerraSAR-X and the US satellite NFIRE, shall demonstrate the performance and advantages of laser communication.

Inter-satellite communications using laser based optical links
SPIE Proceedings, 2007Laser Communications offer a viable alternative to established RF communications for inter-satellite links and other applications where high performance links are a necessity. High data rate, small antenna size, narrow beam divergence, and a narrow field of view are characteristics of laser communications that offer a number of potential advantages ...

Galileo POD using optical inter-satellite links: A simulation study
Advances in Space Research, 2020Abstract In this simulation study the benefit of optical two-way inter-satellite links (OISL) between the Galileo satellites for orbit determination is discussed. Different link scenarios are analyzed in combination with Global Navigation Satellite System (GNSS) observations and a ground station network of seven or 16 stations, respectively.
