The effects of ionospheric scintillation on the performance of a UHF (240 MHz) satellite communications link are deduced from experimental data. Scintillation data from the polar cap region and the auroral oval region taken during the 1980-81 period are presented. The performance of the Air Force Satellite Communications (AFSATCOM) digital data satellite link is described for two highlatitude sites. The AFSATCOM system uses noncoherent binary frequency shift keying (FSK) modulation at 75 b/s and matched filter detection.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
