Satelles

Satelles is an American technology company that develops satellite-based positioning, navigation and timing (PNT) services. It is best known for creating the technology behind Iridium PNT, a commercial service delivered over the Iridium low Earth orbit (LEO) satellite constellation. Satelles was founded in 2013 and is headquartered in Herndon, Virginia. Its core innovation is the use of the Iridium satellite network's powerful, crosslinked L-band signals to provide time and location data that works indoors, at sea, in the air, and during GPS or GNSS outages, interference, spoofing or jamming. The company's flagship offering is the Iridium PNT service, which Satelles developed and which Iridium Communications commercialized. The service is marketed to industries that cannot afford downtime, including 5G network synchronization, data centers, financial markets, maritime operations and government applications. Satelles also supplies the Iridium PNT ASIC, an 8 mm x 8 mm chip that enables resilient, secure primary or backup PNT capabilities in an ultra-compact form factor, supporting standalone Iridium PNT receivers or hybrid Iridium + GNSS solutions. Satelles operates as a subsidiary of Iridium Communications Inc., a publicly traded satellite communications company (NASDAQ: IRDM). The relationship gives Satelles access to Iridium's global network of crosslinked LEO satellites and its 500+ industry partnerships. Satelles' technology is positioned as a complement and backup to traditional GNSS, addressing the growing demand for resilient PNT in critical infrastructure, communications and transportation.

Satelles was founded in 2013 and is headquartered in Herndon, Virginia. The company developed a novel approach to positioning, navigation and timing (PNT) by leveraging the Iridium satellite constellation's powerful L-band signals, which are approximately 1,000 times stronger than GPS signals. This allows Satelles' technology to work indoors, in urban canyons, and in environments where GPS/GNSS signals are degraded, jammed or spoofed. Satelles initially offered its own Satellite Time and Location (STL) service. In 2023, Iridium Communications acquired Satelles and integrated its technology into the Iridium portfolio as Iridium PNT. The acquisition aligned with Iridium's strategy to expand beyond voice and data into resilient PNT services for critical infrastructure. Following the acquisition, Satelles operates as a subsidiary of Iridium Communications Inc. (NASDAQ: IRDM). The Iridium PNT service is delivered over Iridium's global network of crosslinked low Earth orbit (LEO) satellites. It provides accurate time and location data that supports 5G network synchronization, data centers, stock markets, maritime operations, aviation, defense and government applications. In 2024, Iridium introduced the Iridium PNT ASIC, an 8 mm x 8 mm chip designed to simplify integration of resilient PNT into a range of devices, supporting standalone Iridium PNT receivers or hybrid Iridium + GNSS solutions. The ASIC outputs NMEA 0183 interface standard messages and includes built-in RF and power regulators. Satelles' technology is positioned as a complement and backup to traditional GNSS, addressing the growing demand for resilient PNT in critical infrastructure, communications and transportation. The company continues to operate under the Iridium brand, with its technology forming a key part of Iridium's service offerings.
