LYNX VBN GPS-denied Navigation

LYNX VBN is a GPS-denied, Vision Based Navigation system that combines image processing, nonlinear sensor fusion, and machine learning techniques to deliver a flexible VBN solution with demonstrated performance over a wide-range of terrain types, cloud conditions (7/8 broken cloud cover), day/night operation, and precipitation effects including rain and snow cover. The LYNX VBN system delivers a real-time, low-latency solution with industry-leading accuracy and continuity. The LYNX VBN can be enhanced with multi-source observations as available including IMU, multi-constellation GNSS, 3D Mag, BaroAlt, RadarNav and others.


LYNX VBN is available as a stand-alone sensing + processing kit or can be installed in a host system as a Docker container.
