Low Weight Small Size FOG Based INS of class 1 °/h

iNAT-FSSG-1 is a light weight small-size accurate fiber optic gyro (FOG) based INS of class 0.1 deg/hr AllanVariance bias stability and 1 deg/hr performace over full temperture range, consisting of 3 robust fiber optical gyros and 3 MEMS servo accelerometer axes, integrated all frequencies / all constellations GNSS Receiver (GPS, GLONASS, GALILEO, BEIDOU; RTK), wheel sensor interface and an advanced 42+ state Kalman filter based INS/GNSS loosly or tightly coupled data fusion.

iNAT-FSSG-1-DA is based on the same hardware, but additionally it supports a dual-antenna GNSS based true North reference. 

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:

• Power supply and EMI-EMC protection qualified to MIL-STD-704D / MIL-STD-461E / MIL-STD-810G / DO160E, used also in military aircrafts
• Modular system architecture: customized applications can be integrated by iMAR easily (please contact our sales engineers 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); SDK for Integration of user specific functionallity (e.g. vehicle trajectory Controller) available under RT-LINUX.
• ROS-2, Python, C++ SDK supported
• Best of cass SWAP / SWAP-C
• iNAT-FSSG is not subject of ITAR control or any other export control

Note:

Following our proven design philosophy and technical code of conduct for our products and solutions, only the physics determines the behavior of iMAR‘s measurement systems. Our real-time output of our systems and solutions is achieved through the intelligent signal processing invented by our experienced engineers, not by AI (artificial intelligence).
Experienced customers do not entrust the success of critical or general missions to the heuristic decisions of any AI, but rather experience the highest reliability, accuracy and availability of iMAR solutions in their daily use, based on our mathematically and physically precise and traceable results.
