The INS-FI is a state-of-the-art GNSS-aided inertial navigation system (INS) that incorporates tactical-grade fiber optic gyroscopes and MEMS accelerometers to provide high-accuracy horizontal and vertical position, velocity, and absolute orientation (heading, pitch, and roll) data.

Featuring a choice of dual-antenna multi-constellation GNSS receivers from NovAtel, u-blox or Septentrio, it is ideal for a wide range of UAV (unmanned aerial vehicle), UGV (unmanned ground vehicle) and USV (uncrewed surface vessel) applications.

The rugged unit is IP67-rated for ingress protection against dust and water, and has been designed to MIL-STD-461 standards for EMC, EMI, and ERD protection and to MIL-STD-810 standards for environmental protection.
