PETRA 3000
The PETRA 3000 family of inertial navigation systems, equipped with embedded GNSS receivers, is designed for high-precision pointing, localization, and navigation in both new and retrofit land vehicle programs. Featuring a maintenance-free design and rugged construction, PETRA 3000 meets MIL-STD-810F and MIL-STD-461F standards, ensuring durability in demanding environments.
These ITAR-free inertial sensors incorporate advanced Kalman Filter algorithms, providing exceptional accuracy and reliability, even in GNSS-denied or highly challenging conditions.
