They consist of 3 airborne grade ring laser gyro axes and 3 servo accelerometer axes, integrated all-frequencies / all-constellations GNSS Receiver (GPS, GLONASS, GALILEO, BEIDOU), wheel sensor interface and an advanced 42+ state Kalman filter based INS/GNSS/ODO 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. The full accuracy range of the members of the iNAT family from economic to high-end can be found here:
Applications: GNSS aided navigation, free inertial Navigation (air, land, sea, subsea), attitude heading reference (AHRS), surveying (LIDAR, SAR etc.), 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: RS422 (UART and HDLC / SDLC) Interfaces, CANaero / ARINC825 / CAN, ARINC429, Ethernet (TCP/IP and UDP), SYNC-I/Os
Data Output rate up to 400 Hz (each data log separately adjustable)

further parameters. see datasheet (link below)
Integrated 42+ state tightly or loosly coupled data fusion
Internal all-frequencies / all-constellations GNSS engine, up to GPS+GLONASS+GALILEO, RTK, L-Band; SAASM / M-code capability available as optional integrated hardware
Internally up to 128 GByte non-volatile memory for data storage
Power Supply: 10...36 V DC, < 30 W; overvoltage protected up to 60 V; 50 ms hold-up time according to DO160E.
Modular System architecture: customized applications can be integrated by iMAR easily (please contact our sales engineers for Details, e.g. for the available SDK under RT-LINUX or QNX). 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 DO160G / MIL-STD-704F / MIL-STD-461G / MIL-STD-810G
iNAT-RQT is not ITAR controlled. iNAT-RQT can be operated in most countries worldwide and only a standard dual-use export license is required; no detailed export control required within the EU, Canada, Japan, New Zealand, USA (only EU001 procedure required)
Field proven MTBF of inertial core sensors is 120'000 hrs.
