Inmarsat has selected Northrop Grumman Information Systems of McLean, Va., to provide a signal interference and monitoring system for its Ka-band Global Xpress satellite system, London-based Inmarsat announced in a Feb. 10 press release.

Inmarsat is expected to offer full Global Xpress mobile broadband services worldwide, except for the polar regions, by late 2014. The first of a planned four Global Xpress satellites was successfully launched in December.

Northrop Grummanโ€™s Spectrum Interference and Monitoring System (SIMS) will provide spectrum situational awareness, rapid interference detection and problem resolution, according to the release.

Northrop Grumman developed a similar system for the U.S. Air Forceโ€™s Wideband Global Satcom system, which operates in Ka- and X-band frequencies.

โ€œWe are excited to have Northrop Grumman as a mission partner in providing spectrum monitoring capabilities to our Government customers,โ€ Peter Hadinger, president of Inmarsatโ€™s U.S. government business unit, said in the release. โ€œWe chose an advanced spectrum and interference monitoring system that is based on a common platform to the one used by the U.S. [Department of Defense] to facilitate interoperability and support our commitment to assured access.โ€
