MARITIME COMMUNICATIONS VIA SATELLITES EMPLOYING PHASED ARRAYS

This paper examines the feasibility of providing maritime mobile telecommunications as a new service via satellites. A global system with a capacity of 10 duplex voice/data channels (plus an interrogation/reply channel) per satellite is described. The capability is achieved with a 0-db gain UHF antenna in the ship and a UHF phased array in the satellite, which produces 11 steerable beams, each with 30-db peak gain. The links between satellite and shore are assumed to be a SHF. A dedicated satellite weighs 320 kg, which can be launched with an up-rated Thor-Delta. The prime power requirement of 730 watts is provided by an oriented solar array.
