Satelles is an innovative provider of highly secure satellite-based time and location signals from low Earth orbit (LEO) independent of the Global Positioning System (GPS) and other Global Navigation Satellite Systems (GNSS).

Satelles delivers a solution for global time and location that is completely independent from GPS, and is available today.

Satelles was founded in 2008, and is based in Redwood City, California, with an additional office in Herndon, Virginia.

Satelles provides unique timing and location solutions delivered over the Iridium® constellation of 66 low-earth-orbiting satellites. These timing and location signals are available anywhere on Earth, without the need for local infrastructure, making the system perfect for complementing GPS and other location-based technologies.

Satelles created its Satellite Time and Location (STL) service for the purpose of safeguarding against devastating attacks to GPS/GNSS capable of disrupting or disabling electrical grids, wireless communications networks, financial systems, and other private and public infrastructure in ways that seriously imperil the safety and security of our society.


Satelles has extensive experience and expertise in Global Navigation Satellite Systems (GNSS) such as GPS, including: precision real-time kinematic GPS; various augmentation systems to enhance performance; indoor GNSS signal reception; GNSS and other satellite signal authentication; GNSS and inertial navigation integration.


Satelles is backed by C5 Capital, Iridium Communications and others. The company raised $26M from a "Series C" financing on Oct 9, 2019. The round brings Satelles' total funding to $39M to date.
