Lockheed Martin announced today that it has completed site acceptance testing over the Inmarsat-4 satellite network and delivered the Global Satellite Phone Service (GSPS) gateway in Subic Bay to Inmarsat. This is the final major delivery for the GSPS program contract that was awarded to Lockheed Martin in December 2006.

In addition, Lockheed Martin successfully implemented and integrated the evolution of the Global Mobile Radio (GMR2) standard to GMR2+, providing improved performance and features over the prior generation of Lockheed Martin gateway products.

"The delivery of the final GSPS gateway is the culmination of an intense effort to develop the next generation of hand-held mobile satellite telephony," said Bob Kramer, vice president of Information Systems & Global Services-Defense's Space Solutions Division. "The gateways enable Inmarsat to offer its global subscriber base a high quality and feature rich hand-held mobile satellite service."

As part of the GSPS system Lockheed Martin has provided three gateways - located in Italy, Hawaii, and the Philippines - that will enable Inmarsat to provide global high quality handheld voice, fax and data service, even in remote geographical areas.

Lockheed Martin is a leader in the development of mobile satellite ground technology for both military and commercial users.

Headquartered in Bethesda, Md., Lockheed Martin is a global security company that employs about 140,000 people worldwide and is principally engaged in the research, design, development, manufacture, integration and sustainment of advanced technology systems, products and services. The corporation reported 2008 sales of $42.7 billion.
