TrustPoint demonstrates GPS-independent navigation signals to orbit

TrustPoint has transmitted its first Low-Earth Orbit Navigation System (LEONS) time-transfer and tracking signals from a ground node to spacecraft in orbit. The milestone advances the development of commercial navigation infrastructure independent of GPS.

GNSS satellites require knowledge of their own time and orbital position to provide accurate data to Earth-based users. Most LEO spacecraft currently rely on GPS or medium-Earth orbit (MEO) signals for that information. Interference and jamming are increasingly affecting these LEO connections, degrading or blocking signals.

LEONS provides GPS-independent time transfer and orbit tracking. Initially developed for TrustPoint’s planned constellation, the system can be adapted for other LEO operators requiring timing and navigation for their spacecraft. The ground-to-space infrastructure is designed to support a GPS-independent PNT layer in orbit.

“With the pace of modern threats accelerating, the difference between concepts and capabilities matters,” said Nicole Hilliard, director of government programs at TrustPoint. “This milestone demonstrates that commercial partners can field resilient, GPS-independent PNT capabilities that strengthen national security architectures and justify continued investment in companies that deliver.”

The demonstration supports TrustPoint’s participation in the SpaceWERX AltPNT Challenge, which awarded the company two contracts to develop alternative PNT capabilities. The program seeks to deploy new options for precise, dual-use PNT systems.
