Multibeam array designed for use in a maritime system using an OTS platform

The study, based on actual hardware specifically developed for a multibeam array, has been concerned with the definition of a payload compatible with the requirements of a second generation maritime system. The proposed payload designed to operate in an OTS spacecraft has the following performance. 19 beam global coverage, give 70 Maritime channels having 52.4 dB Hz quality in deep fades. Mass of payload incl. antenna, 112 kg; d.c. power consumption, 334 W; Operational life time, 7 yr.
