The iNAT-RQT-400x is a lfamily of ight weight small-size high accurate advanced RLG based INS. It is available in three performance classes:
iNAT-RQT-4001: 0.0020 deg/sqrt(hr) / 0.004 deg/hr / 0.05 mg
iNAT-RQT-4002: 0.0025 deg/sqrt(hr) / 0.007 deg/hr / 0.75 mg
iNAT-RQT-4003: 0.0050 deg/sqrt(hr) / 0.010 deg/hr / 0.10 mg
They consist 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 ring laser technology provides a well-proven and mature long time true north and exceptional navigation accuracy also under harsh environmental conditions (temperature gradients, vibration) where other gyro technologies are already significantly limited due to certain physical effects.
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.
