PETRA
The PETRA family of GNSS-aided inertial navigation systems is designed for high-precision pointing, localization and navigation applications in new and retrofit land vehicle programs, featuring a maintenance-free design and rugged construction rated to MIL-STD-810F and MIL-STD-461F standards.
The ITAR-free inertial sensors utilize advanced Kalman Filter algorithms to ensure superior accuracy and performance even in highly challenging and GNSS-denied environments.
