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 ...

Inter-Satellite Link (ISL) refers to the communication link between satellites, which can replace the ground relay station to do the autonomous operation of satellite constellation. This chapter provides two kinds of ISL antennas with beam scanning capability: the movable spot-beam reflector antenna and the phased array antenna.

Inter-satellite links for cubesats
2013 IEEE Aerospace Conference, 2013Realizing inter-satellite links is a must for ensuring the success of cubesat swarm missions. Nevertheless, it has hardly been considered until now. The communication systems for cubesats have to deal with a few peculiar demands regarding consumed power, geometry and throughput.

Distance estimation in OFDM inter-satellite links
Measurement, 2020Abstract One of the practical solutions for space deployment of large-scale scientific instruments is satellite formation flying. In this type of space mission, several smaller satellites have the ability to interact and cooperate with each other via inter-satellite links (ISL) for tasks commonly performed by a larger and more complex satellite ...

Inter-satellite laser link simulation analysis
SPIE Proceedings, 2015The characteristic of satellite communication link was firstly described and four application modes were put forward. By comparison, it is suggested that microwave link is used in satellite-to-ground communication and laser link is used in inter-satellite communication. Secondly the condition and composition of laser link establishment was analyzed and

Inter-satellite links for satellite autonomous integrity monitoring
Advances in Space Research, 2011Abstract A new integrity monitoring mechanisms to be implemented on-board on a GNSS taking advantage of inter-satellite links has been introduced. This is based on accurate range and Doppler measurements not affected neither by atmospheric delays nor ground local degradation (multipath and interference). By a linear combination of the Inter-Satellite

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.
