The completion of the Iridium NEXT campaign comes as the final two satellites required to complete the network refresh were activated on February 5th at approximately 2:15 p.m. EST. With a fully operational constellation, featuring 66 new Iridium satellites and no further launches planned, Iridium has concluded its nearly decade-long capital-intensive program that created an upgraded network both in space and on the ground.

After spending several hundred million dollars per year to build and deploy the new network, Iridium expects capital costs to decrease to approximately $35 million per year, with revenues continuing to grow as the company expands into newer revenue streams like broadband, IoT and hosted payloads.

First announced in 2010, the Iridium NEXT campaign featured eight launches with SpaceX. In total, 81 satellites were built by prime contractor Thales Alenia Space, of which 75 were launched, with 66 in the operational constellation and nine serving as on-orbit spares. Thales Alenia Space was responsible for design and integration of the new satellites, including launch and early operations testing in partnership with Iridium’s team at the company’s Satellite Network Operations Center in Virginia.

The upgraded Iridium constellation enables never before possible services such as the Aireon global aircraft tracking and surveillance system and Iridium Certus, the company’s latest broadband service, which launched commercially in January 2019. The upgraded network is also fully compatible with the original satellite constellation’s services, a notable accomplishment given the size and scope of the upgrade.

Jean-Loic Galle, CEO of Thales Alenia Space remarked: “The 75 in-orbit satellites are working very well, and the overall end-to-end performance improvement for existing customers is dramatic. Two years after the first launch, Iridium NEXT, one of the most sophisticated communication systems in the world, is now totally deployed and fully operational. All the satellites are interconnected, and we have ensured a continuity of service without any interruption.”

The Iridium Certus 9770 transceiver, also introduced during today’s press conference, is a game changer for satellite IoT, aviation, maritime and consumer services, enabling low-cost, small devices that can make more efficient and higher speed connections than its predecessors. Built on the Iridium Certus technology platform, applications and devices made with the new transceiver will feature a range of speeds optimized for efficiently sending data to and from the user, typically in the range of less than 100kbps.

The Iridium Certus 9770 is the first in a series of new devices that will augment Iridium’s existing transceivers with approximately the same form-factor as existing narrowband antennas used widely today in aviation, maritime, IoT and land-mobile markets, but using native IP technology at up to 35 times the speed as current devices. This supports telemetry, pictures, high-quality voice calling, emails, internet access and more, at highly competitive prices. Select licensed manufacturers of Iridium can expect to receive prototypes of the device around mid-2019.

The Iridium satellite network is comprised of 66 crosslinked satellites that create a web of coverage around the entire planet. Unlike other satellite systems, Iridium’s crosslinked architecture enables real-time transit of data to and from any location on the globe without the need for abundant ground stations and allows it to maintain consistent, high-quality coverage, including over the oceans and polar regions.
