Global satellite IoT subscriber base grew to surpass 3.9 million in 2021
Satellite connectivity provides a complement to terrestrial cellular and non-cellular networks in remote locations, especially useful for applications in agriculture, asset tracking, maritime and intermodal transportation, oil and gas industry exploration, utilities, construction and governments. Both incumbent satellite operators and more than two dozen new initiatives are now betting on the IoT connectivity market. This new study covers a total of 44 satellite IoT operators.
Iridium, Orbcomm, Inmarsat and Globalstar are the largest satellite IoT network operators today. Iridium grew its subscriber base by 21 percent in the last year and reached the number one spot serving 1.3 million subscribers. Originally a dedicated satellite operator, Orbcomm has transitioned into an end-to-end solution provider, delivering services on its own satellite network as well as being a reseller partner of Inmarsat and others. At the end of 2021, the company had 1.1 million satellite IoT subscribers on its own and Inmarsat's networks.
At the same time Globalstar reached 0.42 million subscribers. Other players with connections in the tens of thousands include for instance Kineis in France and Thuraya in the UAE. In addition to the incumbent satellite operators a number of new initiatives have appeared on the market recently. Examples of some high-profile projects are Astrocast, AST SpaceMobile, CASC/CASIC, E-Space, Fleet Space Technologies, Hubble Network, Kepler Communications, Kineis, Ligado Networks, Lynk, Myriota, Omnispace, Skylo, Swarm Technologies (SpaceX) and Totum. Many of these are based on low-earth orbit nano satellite concepts.
