Calian SED was responsible for all aspects of the I5 Global Xpress Gateway systems including the design, procurement, integration, installation and test of Inmarsat’s next-generation Ka-band satellite program. Six systems were provided worldwide with three systems acting as primary sites and three systems provided for diversity/backup operations.
Supplied on a turnkey basis, the system includes identical equipment for all primary and backup sites that are used to support communications operations at Ka-band. Telemetry, Tracking & Command (TT&C) services are also supported.
Each system included a 13.2m Ka-band monopulse limited motion antenna complete with an antenna control system and fully redundant communications transmit and receive equipment chains. Each site also provided redundant TT&C baseband equipment and transmit equipment chains. Also included was measurement hardware for Uplink Power Control pilot measurements and carrier equalization and a monitor and control system.
