"Internet from Space" without Inter-satellite Links
Proceedings of the 19th ACM Workshop on Hot Topics in Networks, 2020Buoyed by advances in space technology, several firms are planning satellite constellations to offer broadband Internet service. While these developments are happening quickly, there are also many uncertainties about the design of these networks. A key open question is whether or not they will incorporate direct connectivity between satellites, instead

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.

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 ...
