Fifth successful Iridium NEXT launch brings Iridium Certus closer

Friday 30th of March saw Iridium edge closer to the completion of their Iridium NEXT satellite constellation following a fifth successful launch. In the coming months, Iridium will launch Certus, their new high speed L-Band communications service, of which Satcom Global is a maritime launch partner. You can read Iridium's latest press release below:

Iridium Communications Inc. (NASDAQ: IRDM) announced today that at 7:13:51 am PDT (14:13:51 UTC) SpaceX successfully launched the fifth set of 10 Iridium NEXT satellites into orbit from Vandenberg Air Force Base in California. All 10 new satellites have successfully communicated with the Iridium Satellite Network Operations Center and are preparing to begin testing. Shortly before launch, the Iridium network met a major milestone as it surpassed 1 million active subscribers. This continues a trend of significant growth and serves as a testament to the reliable, resilient and uncompromising nature of the Iridium network.

Paving the way for Iridium’s growth is the Internet of Things (IoT), where Iridium has established itself as the satellite network of choice to keep “things” connected beyond the limits of cellular coverage. More than half of the subscribers on the Iridium network are IoT devices, delivering a wide variety of solutions by hundreds of licensed technology partners. These devices are designed to do everything from tracking endangered species and monitoring power lines to controlling shipping container temperature levels or serving as tsunami warning systems. Further positioning the company for success is the Iridium NEXT satellite constellation, which is now well more than half way completed. Once fully deployed later in 2018, the constellation will blanket the entire earth with its new capabilities like the Iridium CertusSM L-band broadband service and AireonSM global aircraft surveillance and tracking.

“It’s a unique coincidence that we passed the one million subscribers mark right at this launch, and it’s particularly exciting because we’ve surpassed this milestone earlier than we had anticipated,” said Matt Desch, chief executive officer at Iridium. “The new satellites and services we’re launching and continued strong subscriber growth are cementing our position as an industry leader and critical global communications platform and underscore the significant transformation we’ve undergone as a company over the last 10 years. This truly is a testament to the trust our partners and customers have in our network, which is only going to continue growing as the deployment of the Iridium NEXT constellation nears completion.”

To date, Iridium has completed five launches of 10 Iridium NEXT satellites, all with SpaceX from Vandenberg Air Force Base in California. A total of eight Iridium NEXT launches are currently planned with SpaceX delivering a total of 75 new satellites to orbit. In total, 81 satellites are being built, with 66 in the operational constellation, nine serving as on-orbit spares and six as ground spares.

The first stage booster for today’s launch was previously flown during Iridium-3 in October 2017, making this the second Iridium NEXT launch to use a flight-proven Falcon 9 rocket. Each launch strategically delivers new satellites to specific orbital planes to ensure the earliest possible completion of the constellation. The Iridium network is comprised of six polar orbiting planes, each containing 11 operational, crosslinked satellites, for a total of 66 in the active constellation. The 10 Iridium NEXT satellites launched today were successfully delivered to orbital plane one where they will replace first generation satellites over the next 30 days.

Iridium NEXT is the company’s $3 billion, next-generation, mobile, global satellite network scheduled for completion in 2018. Iridium NEXT will replace the company’s existing global constellation in one of the largest technology upgrades ever completed in space. It represents the evolution of critical communications infrastructure that governments and organizations worldwide rely on to drive business, enable connectivity, empower disaster relief efforts and more.
