This key improvement ensures added flexibility and reliability so we can provide our growing customer base with the best possible service and connectivity on the world's farthest reaching network, today and well into the future on Iridium NEXT." ~ John RODDY Executive Vice President, Global Operations and Product Development, Iridium
