Terrestar Feederlink Earth Station (FES)
Calian, Advanced Technologies provided the Feederlink Earth Stations for TerreStar’s Satellite Beam Access Subsystem (SBAS). Under contract to HUGHES, Calian, Advanced Technologies designed, developed, procured, assembled, tested, integrated, delivered, installed, and commissioned two Feederlink Earth Stations. Each FES contains banks of IF Channel Units, RF communications equipment, and Telemetry, Tracking, and Command (TT&C) RF equipment, all in fully redundant configurations, in addition to redundant tracking antennas. A Monitor and Control System (MCS) and Uplink Power Control (ULPC) was also provided. The FES’s key function is to provide the interface between the satellite payload antenna feeds and the GBBF (Ground-Based Beam Forming) equipment.
ICO Global Communications RF Subsystem (RFS)
Calian, Advanced Technologies provided the RF Subsystem (RFS) for use in the ICO Gateway. ICO’s network was designed to provide wireless voice, data, video, and/or Internet service throughout the United States on mobile and portable devices.
Under contract to HUGHES, Calian, Advanced Technologies designed, developed, procured, assembled, tested, integrated, delivered, installed, and commissioned the RF Subsystem.
LightSquared Feederlink Earth Station
Calian, Advanced Technologies provided the Feederlink Earth Stations (FES’s) for LightSquared’s next generation of satellites. The new satellites depend on Ground-Based Beam Forming to deliver a variety of voice and data services across North America.
Calian, Advanced Technologies provided four Ku-band FES’s under contract to Boeing that operates with the LightSquared SkyTerra 1 satellite. Each FES provides the communications traffic-carrying feeder links to the satellite, while two of the four stations also provide TT&C capabilities. Each station has a dedicated 11.3m primary antenna per satellite with a single 7.3m antenna provided for redundancy. The uplink and downlink RF chains also feature highly redundant systems to achieve exceptional system availability.
