Ground-to-satellite laser communication experiments

IEEE Aerospace and Electronic Systems Magazine, 2008
Ground-to-satellite laser communication experiments between the optical ground station located in Koganei, central Tokyo, and a low earth orbit (LEO) satellite were jointly performed by the Japan Aerospace Exploration Agency and the National Institute of Information and Communications Technology.

Adaptive power control for satellite to ground laser communication

International Journal of Satellite Communications and Networking, 2007
AbstractWe develop an adaptive power control algorithm to facilitate satellite to ground laser communication through turbulence fading channels. Adaptive control is a powerful tool that improves energetic gain of the satellite laser. We use discrete laser transmitter intensity levels in our control algorithm. A novel recursive technique defines optimal

Enhanced ATM for satellite laser communication networks

IEEE Transactions on Aerospace and Electronic Systems, 1999
Satellite networks are one of the most emergent areas in commercial communication. Today about twenty serious consortiums (such as Iridium, Teledesic, Globstar, and Celestri) develop satellite communication networks. In the new generation of satellite networks, laser will be used as a communication link between the satellites in order to get wider ...

Adaptive Optics for Satellite Laser Communications

2023 Optical Fiber Communications Conference and Exhibition (OFC), 2023
The development of laser communication technology between satellites and ground stations has been paid attention recently. On the other hand, the laser communication between satellites and ground stations is always affected by the atmospheric condition.

Silicon photonic receiver for satellite laser communication terminals

Optics Letters, 2022
We report the optical performance of a photonic receiver for laser communication applications. The receiver is composed of 14 × 12 grating coupler arrays. The received optical signal power will be combined electrically via germanium photodiodes. The photonic receiver is designed for 20-µm to 30-µm mode field diameter (MFD) input sources.

Laser satellite communications with adaptive optics

SPIE Proceedings, 2005
Laser satellite communications (LCS) appear to have potential applications in the future global communication network. However, bidirectional ground-to-space link performance is degraded by atmospheric turbulence. This paper presents the simulations results of laser uplink and downlink propagation through atmospheric turbulence based on turbulence ...
