Dynamic Planning of Inter-Plane Inter-Satellite Links in LEO Satellite Networks

ICC 2022 - IEEE International Conference on Communications, 2022
Low Earth Orbit (LEO) satellite constellations are promising to provide global coverage and low latency communication by deploying a large number of small satellites and widely establishing Inter-Satellite Links (ISLs). However, due to the high motion of

Topology Design for GNSSs Under Polling Mechanism Considering Both Inter-Satellite Links and Ground-Satellite Links

IEEE Transactions on Vehicular Technology, 2022
Inter-satellite links (ISLs) are adopted in global navigation satellite systems (GNSSs) for high-precision orbit determination and space-based end-to-end telemetry telecommand control and communications.

Inter-satellite laser link simulation analysis

SPIE Proceedings, 2015
The 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

Optical inter-satellite and feeder links

2017 IEEE International Conference on Space Optical Systems and Applications (ICSOS), 2017
Big data is shaping today's live in many aspects, terrestrial as well as celestial. High data rates are essential for Earth Observation satellites and pre-requisite for High Throughput Satellites and Constellations with broadband data services. Optical communication offers high capacity data transmission for satellites and is available and already ...

A Review on Inter-satellite Link in Inter-satellite Optical Wireless Communication

Journal of Optical Communications, 2017
AbstractIn this paper, inter-satellite optical wireless communication (IsOWC) system is proposed, one of the imperative utilizations of free space optics/wireless space optics (FSO)/WSO innovation. IsOWC frameworks give a high bandwidth, small size, small weight, low power and minimal effort different option for present microwave satellite frameworks ...

Inter-satellite links for satellite autonomous integrity monitoring

Advances in Space Research, 2011
Abstract 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, 2006
Summer 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.

Satellite Navigation Inter-satellite Link Technology

2020
Inter-satellite link (or Crosslink) refers to the link between satellites, or the link between spacecraft in a more generalized sense. Its main functions include inter-satellite communication, data transmission, inter-satellite ranging, and inter-satellite TT&C.
