R4 Integration, Inc. (R4), the premier provider of airborne roll-on/roll-off communication systems for U.S. and partner government aircraft;and Inmarsat, the world leader in global, mobile satellite communications, today announced that Inmarsat has given type approval for the R4 C-130 Multi-Purpose Hatch System (MPHS) for use over the Inmarsat Global Xpress network.

Global Xpress is the world’s first and only, globally available, seamless mobile wideband service. In U.S. government operation since July 2014, Global Xpress has established itself as the gold standard for reliable communications across land, air and sea for assured mobile connectivity and interoperability with government satellite systems.

The R4 MPHS is a low-profile Ka-band integrated system that can be configured with virtually any type antenna or sensor that meets the size constraints of the MPHS. The system is fully interoperable with military Ka-band systems and optimized for use over the Global Xpress constellation.

Developed for mission-critical roll-on/roll-off requirements of the most demanding government special operations forces and other government customers, the MPHS accesses various Ka-band networks to provide enroute Command, Control, Computers, Communications, Cyber, Intelligence, Surveillance and Reconnaissance (C5ISR) support to airborne users on all C-130/L-100 aircraft variants.

Steve Gizinski, President, Inmarsat Government commented, “The rapidly growing military, government and commercial customer adoption of Global Xpress is a testament to its exceptional assured global mobile connectivity and seamless interoperability with military satellite resources. With R4’s MPHS, military users now have a very compact, Roll-On/Roll-Off solution to support airborne critical communications-on-the-move connectivity requirements.”

John Parsley, President of R4 stated, “Our smart, integrated, hybrid solution meets the fast-changing intel requirements of airborne forces. Inmarsat’s Global Xpress provides the peak of seamless SATCOM-on-the-move operability for mission-critical operations based on our MPHS solution.”
