Investigation of the Influence of LEO Constellation Dynamics on Optical Inter-satellite Links

2023 IEEE International Conference on Space Optical Systems and Applications (ICSOS), 2023
Low Earth orbit (LEO) satellite constellations are seen as a future extension of today’s terrestrial fiber networks, providing network services in remote and underserved areas. In order to achieve true, seamless connectivity on a global scale, satellites

Enhanced Orbit Determination of GNSSs with Optical Inter-satellite Links

2019 9th International Conference on Recent Advances in Space Technologies (RAST), 2021
Inter Satellite Links (ISL)are essential to connect Satellites operating in a constellation. If these ISLs could manage high data rates in Gigabit per seconds the network becomes a broadband connectivity services. New possibilities for data exchange and independencies from ground networks are offered.

DP-QPSK for Optical Inter-Satellite Links in a Broadband Constellation Network

2021 7th International Conference on Space Science and Communication (IconSpace), 2021
This paper presents a spectral efficient dual polarization quadrature phase shift keying (DP-QPSK) modulation format in an optical inter-satellite link (OISL). The model is simulated to operate in a low Earth orbit (LEO) satellite broadband constellation
