Acquisition, Scanning and Control Technology for Inter-satellite Laser Communication
2021 IEEE 16th Conference on Industrial Electronics and Applications (ICIEA), 2021Due to the complex space environment, it is very difficult to establish communication links between satellites efficiently and quickly. Considering laser power limitation and environmental conditions, the gazing/scanning method is selected to achieve inter-satellite laser communication. Firstly, this paper establishes the theoretical model of the field

Space-based laser systems for inter-satellite communications
SPIE Proceedings, 2012Space-based optical communications using satellites in low earth orbit (LEO) and Geo synchronous orbits (GEO) hold great promise for the proposed Internet in the Sky network of the future. Building high speed communications network using optical links in space has proven to be an extremely complicated task and many such schemes were tried without ...

Demonstrations of ARTEMIS-OICETS Inter-Satellite Laser Communications
24th AIAA International Communications Satellite Systems Conference, 2006Japan Aerospace Exploration Agency (JAXA) developed the Optical Inter-orbit Communication Engineering Test Satellite (OICETS) for the purpose of establishment of the base technology of a next-generation space communication network. On 23rd August 2005, OICETS was successfully launched and thrown into a polar sun synchronous orbit at the altitude of 610

Quick topological method for acquiring the beacon in inter-satellite laser communications
Applied Optics, 2014Background starlight can lead to some spot noise in the image collected by a CCD, disturbing the beacon acquisition in inter-satellite laser communications. Removing the spot noise takes much time by using the existing method that is based on the reference star calendar table. We present a novel method to reduce the processing time in this paper.

Inter-satellite communications using laser based optical links
SPIE Proceedings, 2007Laser Communications offer a viable alternative to established RF communications for inter-satellite links and other applications where high performance links are a necessity. High data rate, small antenna size, narrow beam divergence, and a narrow field of view are characteristics of laser communications that offer a number of potential advantages ...

Optical System in Laser Inter-Satellites Communication
Advanced Materials Research, 2014We know that Inter-satellites communica-tion is a very important to us.However, real global coverage can only be achieved by satellite systems. Satellites communication is the most important mean of the communication network. The traditional satellites communication and inter-satellites links are built by microwave.

Research on denoising in WDM laser inter-satellites communication system
SPIE Proceedings, 2006This paper proposes a method of wavelet analysis for de-noising at receiver system in WDM laser inter-satellites communication. Background noises such as galactic noise, sunlight and etc make the received power reduce. The noisy signal is decomposed using wavelets and wavelet packets; then is transformed into wavelet coefficients and the lower order ...
