Lockheed Martin (NYSE: LMT) 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. 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.
