iNAT-MSLG-5 is a light weight accurate MEMS based INS of class 0.1 deg/hr (AllanVariance bias stability) and 5 deg/hr bias performace over full temperture range, consisting of 3 robust MEMS gyros and 3 MEMS servo accelerometer axes, integrated multi-constellation capable GNSS Receiver (GPS, GLONASS, GALILEO, BEIDOU etc.), 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.  

Features

• Applications: GNSS aided 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)
• Dual-antenna GNSS capability to provide true heading also at standstill or during operations without sufficient motion dynamics
• Interfaces: RS422 (UART), CANaero / ARINC825 / CAN, Ethernet (TCP/IP and UDP), ARINC429, SYNC-I/Os
• Data Output rate up to 500 Hz (each data log separately adjustable)
• The very low data output latency of 1 ms and the very low data output jitter of < 1 ms enables the iNAT-MSLG-5 also to be a reliable solution for steering & control of highly automated and autonomous driving vehicles 
• Measurement range:
  +/-480 deg/s, +/-15 g
• Inertial Sensor Performance:
  
  Heading accuracy:
  < 0.05 deg (GNSS aided); 0.01 deg in post-processing (dependent on environment)
  
  Attitude accuracy:
  < 0.05 deg (GNSS aided)

• 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 as FFF by iNAT (Form-Fit-Function replacements)
• iNAT-MSLG-5 is not subject of any export control or ITAR regulations

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.
