Description
New terminals need to be developed for operating with the Inmarsat-S space segment. This poses challenges for example due to thefact that the S-band space segments operate in different polarizations in adjacent spot beams and terminals need to be able todetect the right polarization in each beam. Moreover the enhanced system performance with respect to any other Inmarsatsatellites makes it possible not only to develop broadcast UT receivers, but also to develop much more advanced mobile userterminals which support a suite of services for bi-directional communications. The initial part of the activity will cover astudy of S-band terminals addressing technological issues, e.g. S-band antenna technology, hybrid dual polarisation L and S-bandantennas. The study will focus on the 3 terminal product families: BGAN, GSPS and Broadcast, ranging from possible productintegration to service enhancements (high throughput, powerful return link, etc) achievable with the Inmarsat-
