The SBX SATCOM provides reliable, expandable, high-data-rate communications services to the SBX platform. The service provides dual marine stabilized terminals along with satellite and CONUS teleport services. Each Harris provided terminal is equipped with dual 4.5-meter antennas operating over commercial C-band satellites. The dual antenna terminals provide 360° azimuth coverage around the X-band radar located in the center of the platform. The dual terminals operate over separate satellites to provide redundant SATCOM service between the platform and CONUS Ground-Based Midcourse Defense Communications Network (GCN).

The SBX radar system will be deployed on a mobile, floating platform. Continuous communications between the platform and shore facilities will be provided via a commercial C-band satellite, using a unique redundant dual-antenna system designed and furnished by Harris Maritime Communication Services (MCS) subsidiary. Harris MCS provides satellite communications services to cruise ships, remote land-based locations around the world, and to data collection sites thousands of meters below the ocean’s surface.
