Study of mobile communications payload for Columbus Polar Platforms
Abstract
A communication payload to be embarked on the Polar Platform of the Columbus program, to provide mobile communications services to the polar areas was defined. The time visibility constraints typical of the low altitude orbit of the platform are experienced by users and therefore limit the possibilities of real time operation. However, mail box type communications may be successfully implemented. The system architecture for a low orbit polar platform and the criteria for real time and mail box operations were derived. The system architecture includes the Earth segment and the in-orbit system. Problems relevant to the real viability of the in-orbit system were investigated, defining the service operation conditions and the communications transponder layout. The user terminal architecture was assessed to demonstrate overall program feasibility.
