LO 4 TV broadcast and telecommunications system definition study, volume 1
Abstract
A preliminary system definition study of the proposed 12-14 GHz television broadcasting and telecommunications mission for the Ariane LO4 platform is presented. The broadcasting mission analysis covers Norway, Greenland, and Iceland. It is shown that some degree of uplink power control is required to cover the Greenland/Iceland area. Increasing the range of ALC in the satellite allows greater tolerance of downlink fading. The use of FDMA and TDMA systems for the telecommunications mission is discussed. Recommendations are made for further study, in particular on the atmospheric attenuation model of the area to be covered.
