The first of three Inmarsat 5 Global Xpress satellites being built by Boeing has successfully completed a key system life test. The satellite performed as expected during the spacecraft thermal vacuum test, which simulated the cold, airless vacuum of space.
When operational, the Inmarsat 5 satellites will support Inmarsat’s Global Xpress network, providing vital data connectivity for government and commercial users on land, at sea and in the air. The two remaining satellites, which will complete Global Xpress’ global coverage, are currently in production at Boeing’s Satellite Development Center.
“We remain focused on continuing to complete crucial milestones to successfully deliver this series of satellites,” says Craig Cooning, Vice-President and general manager of Boeing Space & Intelligence Systems. “The Inmarsat 5 series is built on our 702HP model of satellites, which is flight-proven with over 20 spacecraft in orbit.”
