A new report by Swedish market research company Berg Insight states that the global satellite IoT communications market is growing steadily. In 2023, the global satellite IoT subscriber base surpassed 5.1 million, with the number increasing at a compound annual growth rate of 39.2% to reach 26.7 million units in 2028, says the report.
The new study, titled ‘The Satellite IoT Communication Market’ covered a total of 40 satellite IoT operators. According to its findings, only around 10% of the Earth’s surface has access to terrestrial connectivity services, leading to an opportunity for satellite IoT communications. Satellite connectivity provides a complement to terrestrial cellular and non-cellular networks in remote locations, for example 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.
Elaborating on the report, Johan Fagerberg, Principal Analyst at Berg Insight said: “Iridium, Orbcomm, Viasat (Inmarsat) and Globalstar are the largest satellite IoT network operators today.” Iridium grew its subscriber base by 17% in the last year and reached the number one spot serving 1.8 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 Viasat (Inmarsat) and others. At the end of Q4 2023, the company had 715,000 million satellite IoT subscribers on its own and Viasat’s networks. Globalstar reached 0.48 million subscribers. Other players with connections in the tens of thousands include for instance Myriota in Australia, 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, 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.
While some rely on proprietary satellite connectivity technologies to support IoT devices, several are starting to leverage terrestrial wireless IoT connectivity technologies. Examples include OQ Technology, AST SpaceMobile, Omnispace, Sateliot, Galaxy Space, Ligado Networks, Lynk, Skylo and Starlink (3GPP 4G/5G), EchoStar Mobile, Fossa Systems, Lacuna Space, Innova Space and Eutelsat (LoRaWAN), and Hubble Network (Bluetooth). Collaborations between satellite operators and mobile operators that explore new hybrid satellite-terrestrial connectivity opportunities will become common in the next years, expects Berg Insight.
“Skylo has been the most active NTN (non terrestrial network) provider lately for hybrid cellular/satellite offerings working with Deutsche Telekom, BICS, emnify, floLIVE, Monogoto, O2 Telefónica (Germany), Particle, Soracom, Transatel and 1GLOBAL (Truphone). Additional satellite IoT operators partnering with mobile operators and MVNOs include Sateliot, Starlink, OQ Technology, Omnispace, Lynk, Intelsat, Viasat and AST SpaceMobile,” concluded Fagerberg.
