Abstract Inter-satellite optical-wireless communication systems (IsOWC), one of the important applications of FSO/WSO technology, will be deployed in space in the near future. The IsOWC systems provide a high bandwidth, small size, light weight, low power and low cost alternative to present microwave satellite systems. In this paper, we have reported

Pointing Acquisition And Tracking System For Silex Inter Satellite Optical Link
SPIE Proceedings, 1989This paper is concerned with the architecture and functional analysis of the Pointing Acquisition and Tracking (PAT) subsystem of the European Silex program (Semiconductor laser Intersatellite Link Experiment). The Silex scenario is composed of two optical terminals mounted on low earth orbit, and geosynchronous orbit spacecrafts.

Dynamic link attenuation of inter-satellites homodyne BPSK optical communication
SPIE Proceedings, 2014This paper summarizes the results of a dynamic link attenuation probability study in inter-satellites homodyne BPSK optical communication system. The impacts of the pointing and tracking error on the coherence receiving power are investigated analytically.

Receiver design for optical inter-satellite links based on digital signal processing
2016 18th International Conference on Transparent Optical Networks (ICTON), 2016We present a comparison of homodyne and intradyne detection schemes for high-order modulation formats in optical inter-satellite communication systems. The homodyne detection based on optical PLL techniques is numerically investigated for BPSK and QPSK transmission.
