"In this report, a technical assessment of Optical Intersatellite Link (OISL) is done. Variousparameters, such as link range, pointing azimuth and elevation are computed to definespecifications for telescope gimbals and aperture size as well as optical power. These parameters could later serve to identify critical sub-systems of present technology and focus the research activities towards new avenues. In the first part of the report, the characteristics of the most promising satellite constellations are reviewed with respect to intersatellite links. Then orbital analysis are made on Teledesic and Celestri constellations to derive telescope critical parameters such as scanning angles and slew rates. The report continues with a link budget analysis to derive the communication package requirements such as optical power, telescope size, noise level, bit-error rates"--Abstract.
