Assured Position, Navigation and Timing (APNT) from Inertial Labs

Accurate navigation in GNSS-denied or contested environments is paramount for mission success for crews in ground vehicles such as UGVs. The Inertial Labs LEO-Aided IRINS utilizes signals that are 1000x stronger than GNSS to provide absolute positioning for land vehicles. Additionally, Inertial Labs’ proven Tunnel Guide algorithm provides reliable orientation data and mitigates positioning drift derived from inertial sensors in free inertial instances.

Due to environmental or purposeful GNSS outages, uncrewed vessels such as USVs require reliable navigation information without GNSS to perform inspection, monitoring, and surveillance operations. Inertial Labs INSs can work with doppler velocity logs (DVLs) to provide highly accurate velocity information and thus mitigate position errors. Additionally, the IRINS utilizes LEO constellations to provide absolute positioning in GNSS denied environments.

Loitering munitions are increasingly targeted with GNSS interference and therefore resilient PNT is mission critical for these applications. The Inertial Labs INS-U integrates an embedded Air Data Computer (ADC) for precise velocity estimation and positional drift mitigation for aerial applications. For longer-term denied environment, the VINS utilizes map-matching and sensor fusion algorithms to create a robust GPS-denied visual positioning system (VPS).
