Description

Plextek's GPS-Denied Navigation solutions provide resilient alternative navigation (Alt-Nav) technologies that enable reliable positioning when Global Navigation Satellite Systems (GNSS) are degraded, jammed, or unavailable. The system integrates multiple sensing modalities including inertial navigation, visual scene matching, terrain referenced navigation, and radio frequency positioning to maintain navigation accuracy in contested environments, urban canyons, subterranean spaces, and other GPS-denied scenarios.
