High Performance Low Weight / Small Size RLG Based INS of Class < 0.002 °/sqrt(hr)

Attention: For new designs use iNAT-RQT-400x

The iNAT-RQH-400x is a Family of light weight small-size high accurate advanced RLG based INS of class < 0.004 deg/hr / 25 µg, consisting of 3 airborne grade ring laser gyro axes and 3 servo accelerometer axes, integrated GNSS Receiver (GPS, GLONASS, GALILEO, BEIDOU), wheel sensor interface and an advanced 42+ state Kalman filter based INS/GNSS loosly or tightly coupled data fusion.

The iNAT series is used for navigation, guidance and control of vehicles, stabilization of platforms, surveying reference as ground truth etc. in the fields of industrial, automotive, surveying, defense and space applications. The full accuracy range of the members of the iNAT family from economic to high-end can be found here:
