Second GX satellite begins payload testing

Inmarsat Global (Inmarsat) has confirmed that Inmarsat-5 F2 (I-5 F2), the second Global Xpress (GX) satellite, has successfully completed its orbital deployment stages on schedule and is now in the early stages of payload testing.I-5 F2’s payload testing marks the final phase in the satellite's mission and is expected to take approximately three weeks. The testing will take place from Inmarsat’s GX gateway site in Nemea, Greece.“These were the final deployments to be performed, signalling the last significant mission risk for the I-5 F2 spacecraft,” commented Michele Franci, CTO, Inmarsat. “Once fully tested, the satellite will be moved into its final orbital location where it will become ready for commercial service. We’re very happy with how the mission has progressed and with preparation already underway for the Inmarsat-5 F3 (I-5 F3) launch and mission, we are even closer to turning GX into a truly global service.”“GX Aviation remains firmly on track: it will be available in the second half of 2015," added Leo Mondale, Inmarsat’s president of aviation. “In addition to the successful orbital deployment of I-5 F2, we have successfully completed tests of the Honeywell airborne satellite communications hardware for our GX Aviation service; exceeding performance expectations.”Together with Inmarsat-5 F1 and F2, the third GX satellite, I-5 F3, scheduled to launch before the end of Q2, will complete the world’s first fully globally available Ka-band mobile broadband satellite network through one provider.
