Satelles

Satelles, now part of Iridium's PNT Division, specializes in assured positioning, navigation, and timing (PNT) services. Founded in 2008 and based in Reston, Virginia, the company offers a secure alternative to GPS/GNSS. Its primary service, the Satellite Time and Location (STL) service, became operational in 2016 and broadcasts cryptographically secured timing and location signals via low Earth orbit satellites. The STL service provides critical backup for GPS/GNSS, ensuring resilience against disruptions. It operates independently of ground-based networks, offering global coverage and high-security signals to prevent spoofing and jamming. Satelles serves various sectors, including 5G wireless networks, financial services, data centers, and government infrastructure, focusing on precise timing synchronization and reliable timekeeping. The company fosters a collaborative culture, emphasizing flexibility and transparency in its operations.
