Simulation of BPSK Costas loop for optical inter satellite link
2017 2nd IEEE International Conference on Recent Trends in Electronics, Information & Communication Technology (RTEICT), 2017With the development of high resolution cameras for Earth observation applications, there is increasing demand on a high data rate Satellite communication link. Free Space Optical (FSO) communication is a suitable candidate for such high data rate communication and offers several advantages.

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 ...

Tone-Based Modulation and Demodulation Architectures for Beaconless Optical Inter-Satellite Links
Frontiers in Optics + Laser Science 2025 (FiO, LS)This paper presents AM tone modulation and demodulation methods for SDA OCT compliance, supporting beaconless PAT under low-SNR conditions below –15 dB. Envelope Detection, Analog, and Fully Digital Lock-in Amplifiers are comparatively evaluated.

System analysis for optical inter-satellite link with varied parameter and pre-amplification
2016 International Conference on Advances in Computing, Communications and Informatics (ICACCI), 2016Inter-satellite optical wireless communication (Is-OWC) provides high date rate long distance outdoor links free of licensing issue. There is a line of sight communication which is affected by the alignment of satellite in space. In this paper, the system is designed with pre-amplification in the inter-satellite link to combat the losses with the ...

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.
