iNAT-RQH-400x Advanced Navigation, Surveying & Control System (0.003 °/h, 0.1...0.8 nm/h)

High Performance Low Weight / Small Size INS of Class 0.003 °/h

The iNAT-RQH-4003 is a light weight small-size high accurate advanced RLG based INS of class 0.003 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 15+ state Kalman filter based INS/GNSS loosly or tightly coupled data fusion.


  • Applications: GNSS aided navigation, free inertial Navigation (air, land, sea, subsea), attitude heading reference (AHRS), surveying, UAV, AUV and RPV guidance & control
  • Real-time data output: longitude, latitude, alttude / height, velocty, roll, pitch, yaw / heading, angular rates, acceleration, status, calibrated raw data INS/GNSS (for post-processing)
  • Interfaces: RS485 (UART and HDLC / SDLC) Interfaces, CANaero / ARINC825 / CAN, ARINC429, Ethernet (TCP/IP and UDP), SYNC-I/Os
  • Data Output rate up to 300 Hz (each data log separately adjustable)
  • Measurement range +/-800 deg/s, +/-20 g
  • Heading accuracy 0.025 deg sec lat
    Attitude accuracy < 0.01 deg
    Position accuracy free inertial 0.8 nm/hr
    Position accuracy GNSS aided < 1 m (rms) [S/A off]
    Position accuracy GNSS aided 0.02 m (rms) [RTK available]
  • Bias over temperature 0.003 deg/h / 25 µg
    Noise / ARW 0.0025 deg/sqrt(hr) / 8 µg/sqrt(Hz)
    Bias stability (AV) < 0.002 °/hr, 10 µg @ const. temp.
  • Integrated 15+ state tightly or loosly coupled data fusion
  • Internally up to 32 GByte non-volatile memory for data storage
  • Power Supply: 11...34 V DC, 35 W
  • Modular System architecture: customized applications can be integrated by iMAR easily (please contact our sales for details). So the iNAT can provide arbitrary data and command protocols according to customer requirement, e.g. to substitute other navigation systems by iNAT (e.g. for Form-Fit-Function replacements)
  • EMI-EMC protection and qualification according to DO160E / MIL-STD-704D / MIL-STD-461E / MIL-STD-810G
  • iNAT-RQH is ITAR controlled (see iNAT-RQT-4003 for an ITAR free solution).
