Satelles

What Satelles does

Satelles, Inc. developed and commercialized Satellite Time and Location (STL), a satellite-based positioning, navigation, and timing (PNT) technology that delivers cryptographically secure time and location signals independent of GPS/GNSS. The STL signal rides on the Iridium low-Earth-orbit (LEO) satellite constellation, enabling the service to function indoors, at sea, and in the air — and to maintain integrity during GPS/GNSS jamming, spoofing, or interference events. The company targeted organizations requiring definitive device-location authentication, with a primary use case in protecting data centers and other critical infrastructure from positioning and timing attacks.

The company's go-to-market was B2B, selling PNT authentication as a subscription-style service to critical-infrastructure operators. Pricing was not publicly disclosed. Satelles had secured roughly $54.6M in venture funding across five rounds between 2008 and early 2023, with key backers including C5 Capital and Safar Partners. In April 2024, Iridium Communications acquired Satelles for approximately $115 million, integrating STL into Iridium's PNT service portfolio.

Under Iridium ownership, Satelles' STL technology now anchors a broader PNT service line that includes three product tiers and is marketed into 5G networks, data centers, financial markets, maritime, and government/defense customers. The company has announced 'Project Authentic,' a data-center-focused PNT authentication solution, and is preparing to release the Iridium PNT ASIC — an ultra-compact 8mm-by-8mm chip planned for commercial availability in mid-2026 — that will embed the STL capability into mass-market hardware. The combination of a deployed LEO constellation, miniaturized chip form factor, and growing regulatory focus on PNT resilience positions the Satelles-derived product line for cross-vertical expansion.

Core offering

Satelles develops and provides Satellite Time and Location (STL) technology — a satellite-based positioning, navigation, and timing (PNT) service delivered via the Iridium LEO satellite constellation that produces cryptographically secure time and location signals. The offering serves as a resilient alternative or backup to GPS/GNSS, capable of definitively proving device location indoors, at sea, and in the air, and maintaining signal integrity during spoofing, jamming, or interference attacks. The technology is delivered as subscription-based PNT service packages and, in mid-2026, as an integrated Iridium PNT ASIC chip for embedded device integration.

Product overview

Satelles, acquired by Iridium Communications in 2024 for $115 million, developed the Satellite Time and Location (STL) technology — a satellite-based positioning, navigation, and timing (PNT) solution designed to address vulnerabilities in GPS and GNSS systems. Following the acquisition, Iridium has integrated STL into its PNT service portfolio, offering the technology as a cryptographically secure alternative signal for critical infrastructure protection. The company is developing the Iridium PNT ASIC, a miniature chip scheduled for commercial release in mid-2026, which will enable resilient, secure primary or backup PNT capabilities.
