Taktisk satellittkommunikasjon

Abstract

This report discusses tactical satellite communications, specifically with respect to how Norwegian terrain influences operation of manpack terminals and small vehicular terminals. Special consideration is given to rain attenuation, diffraction and vegetation attenuation. It is found that the use of manpack terminals are of limited value in Norwegian terrain due to low elevation angles of geostationary satellites. On the other hand, with vehicular terminals, this problem is easier to overcome because of increased mobility and due to the fact that the vehicles primary goal merely is to establish a communication link. In fact, this communication link could in many cases be easier to establish via satellite than by a radio link which is normal today
