What Sateliot does

Sateliot (legal name: SATELIO IOT SERVICES, S.L.) is a Barcelona-headquartered, privately-held satellite telecommunications operator founded in 2018 that is building a Low Earth Orbit (LEO) constellation to deliver 5G NB-IoT Non-Terrestrial Network (NTN) connectivity compliant with the 3GPP Release 17 standard. The company operates Europe's first 5G satellite development center — a 2,000+ square-meter Barcelona facility housing a Clean Room (Assembly, Integration and Testing of satellites), Mission Control and Tech Lab — where it designs and manufactures its own satellites, including the Tritó next-generation platform (~150 kg, ~4 m, with the Excalibur regenerative multi-beam payload integrating 4G, 5G NR-NTN and IoT). Its core technological differentiators are Store & Forward onboard data buffering, regenerative on-board signal processing, and a multibeam antenna payload that can simultaneously target multiple regions, all of which allow operation with a lower-density constellation than competing LEO approaches. As of April 2026 the company had six satellites in orbit (after the Revolution mission of August 2024), with five more launches planned for 2026 and 16 additional satellites to be funded by the in-progress €100M Series C.

Sateliot monetizes its network primarily through wholesale 5G NB-IoT satellite connectivity sold to Mobile Network Operators (MNOs) under standard GSMA/3GPP roaming agreements — including Telefónica, Deutsche Telekom, Turkcell, Telenor IoT and VIVO Brazil — enabling operators to extend coverage without deploying new terrestrial infrastructure and end users to connect via existing SIM cards without hardware modification. Pricing is positioned at levels comparable to terrestrial mobile networks to enable mass-market IoT adoption. Secondary revenue mechanics include a Sateliot Certification Program for chipset, module and OEM manufacturers (Nordic Semiconductor, Qualcomm, Creative5), a self-service Tech Lab validation environment, and longer-term managed-services contracts with defense and government customers (notably the Telefónica España 5G NR-NTN alliance for security and dual-use applications). The company reports €270M in precontracts across 400+ clients in 60 countries as of the April 2026 Series C announcement, although recognized revenue is not disclosed and the bulk of the customer pipeline is in the binding-orders and pre-contract stages. Six satellites in orbit deliver the first commercial 5G NTN service, with the wider constellation serving as both an IoT platform and a future 5G NR demonstrator for voice, video and data, with Direct-to-Device capability planned via Tritó satellites launching in 2027.

Core offering

Sateliot operates a Low Earth Orbit (LEO) satellite constellation that delivers 5G NB-IoT Non-Terrestrial Network (NTN) connectivity under the 3GPP Release 17 standard, allowing unmodified commercial IoT devices to connect directly from space through standard Mobile Network Operator SIM cards. The company sells wholesale satellite connectivity to MNOs via GSMA roaming and direct enterprise contracts across agriculture, maritime, energy, logistics, environmental monitoring, mining, oil & gas, and defense/security verticals. It also provides a Certification Program for chipset, module, and device manufacturers and is developing next-generation 5G NR-NTN and Direct-to-Device (D2D) capabilities on the Tritó satellite platform.

Product overview

Sateliot offers a single integrated 5G NTN connectivity platform built around its LEO satellite constellation (the Sateliot LEO 5G NTN Constellation). The core is the Sateliot 5G NB-IoT NTN Connectivity Service, which provides wholesale satellite roaming through Mobile Network Operators and is being extended with 5G New Radio Non-Terrestrial Network (NR-NTN) capabilities, Direct-to-Device (D2D) functionality and Excalibur regenerative multi-beam payloads on the next-generation Tritó satellites. Operational modules include Store & Forward technology, the European Satellite Development Center (with its Clean Room, Mission Control and Sateliot Tech Lab), the Sateliot Certification Program and the Conecta Brasil LEO NTN Program. The roadmap is shaped by a portfolio of EU-funded R&D projects — QUANGO, ETHER, QUDICE, AGRARIAN, VITAS, PLESGINT, FreeGNSSNetwork, ACES, BEAM5 and DMIoT — that progressively extend the platform toward 6G, quantum-secure communications, GNSS-independent positioning and blockchain-enabled anomaly detection.

Direct peers

• Iridium Communications: Iridium is the established MSS satellite operator with global L-band coverage for IoT, voice, and data — Sateliot's most direct competitor in the satellite IoT space. Iridium was one of the named petitioners in the FCC MSS spectrum case alongside Sateliot and is an incumbent whose spectrum rights the FCC preserved in April 2026.
• OQ Technology: OQ Technology operates a 5G NB-IoT NTN satellite constellation and is one of Sateliot's closest direct peers in the standardized 5G NTN IoT space. OQ is a co-partner with Sateliot in Deutsche Telekom's multi-orbit IoT offering, highlighting their parallel positions in the 3GPP NTN ecosystem.
• Skylo Technologies: Skylo provides 5G NTN satellite IoT connectivity using GEO satellite spectrum (via partner satellites) and is bundled alongside Sateliot in Deutsche Telekom's multi-orbit IoT offering. Skylo is a direct competitor pursuing the same standardized NB-IoT NTN market via a GEO architecture.
• Astrocast: Astrocast is a Swiss-listed LEO nanosatellite IoT operator offering bidirectional satellite IoT connectivity for asset tracking, maritime, and agriculture. It is a direct peer in the LEO IoT connectivity market, though using a proprietary (non-3GPP) protocol rather than 5G NB-IoT NTN.

Emerging players

• AST SpaceMobile: AST SpaceMobile is building a space-based cellular broadband network aimed at direct-to-device smartphone connectivity. It is a co-petitioner in the FCC MSS spectrum case with Sateliot and competes for the same 5G NR-NTN D2D opportunity that Sateliot's Tritó roadmap targets from 2027.
• Kepler Communications: Kepler Communications is an emerging LEO satellite IoT operator building a nanosatellite constellation for store-and-forward data services. It is a peer in the satellite IoT connectivity market and was also a co-petitioner in the FCC MSS spectrum case.
• Lacuna Space: Lacuna Space operates a LEO IoT constellation using LoRaWAN-based store-and-forward technology, making it a direct peer in low-power, intermittent satellite IoT connectivity for agriculture, logistics, and environmental monitoring — the same verticals Sateliot targets.

Broad incumbents

• Swarm Technologies (SpaceX): Swarm Technologies, now a SpaceX subsidiary, operates a LEO nanosatellite IoT network. As part of SpaceX, it has access to substantially greater capital and launch capacity than Sateliot, making it a broad incumbent peer in the low-cost satellite IoT connectivity space.
• Thales Alenia Space: Thales Alenia Space is a major European satellite manufacturer and operator with a broad portfolio including IoT, Earth observation, and navigation. It is a broad incumbent peer due to overlapping participation in EU NTN initiatives and 5G/6G R&D projects alongside Sateliot.

Regional players

• EchoStar Mobile: EchoStar (parent of Hughes Network Systems and EchoStar Mobile) operates hybrid satellite-terrestrial networks and holds MSS spectrum across multiple jurisdictions. It is a regional peer in the satellite IoT and MSS space, particularly relevant given the FCC's April 2026 spectrum decision.
