Inter satellite laser communication system.

Laser communication links in space are attractive alternatives to present day microwave links. The system and component technology necessary for successful inter satellite link exists today. In outer space the communication range of free space optical communication is currently of the order of several thousand kilometers suitable for inter satellite service. Out of these modules present in the.

Laser communication links in space are attractive alternatives to present day microwave links. The proposed internet in the sky requires low earth orbit leo and geo. A space based laser communication framework including an inter satellite network has been developed in the past few years. In this system the same laser is used both as a beacon and as a transmitter.

Laser communication in space is free space optical communication in outer space. Leo satellites are able to provide true global coverage ubiquity and quick deployment.

This paper firstly makes an overview of an optical inter satellite communication terminal.

A unique technique of pointing control system for an intersatellite laser communication and ranging link is presented. The laser communication system has a compact structure low power consumption and effective suppression of low frequency and high amplitude angle jitter of the platform. Conclusion with the dramatic increase in the data handling requirements for satellite communication services laser inter satellite links offer an attractive alternative to rf with virtually unlimited potential and an unregulated spectrum. This terminal contains several modules such as transmit assembly receive assembly diplexers mirrors assembly acquisition and tracking sensor optics etc.

It has the potential to bridge interplanetary distances of millions of kilometers using optical telescopes as beam expanders. In this survey we present the various research being conducted in the small satellite community for implementing inter satellite communications based on the open system interconnection osi model. Out of these modules present in the terminal we. Leosat s system using inter satellite laser links for commercial communications is a departure from existing solutions today pairing the speed of fiber with the ubiquity of satellite.
