iCOMBANA: Combat Vehicle Navigation Solutions with Gyro Compassing Capability (dual-use equipment)

Low Weight Small Size FOG and MEMS based INS for Combat Vehicles

iCOMBANA is a family of light weight small-size accurate inertial navigation systems (INS), based on FOG and MEMS sensor technology, of class 0.01...0.1 deg/hr AllanVariance bias stability and 0.1...5 deg/hr bias performace over full temperture range, consisting of 3 robust fiber optical or MEMS gyros and 3 MEMS 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.


  • 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)
  • Interfaces: RS485 (UART) Interfaces, CANaero / ARINC825 / CAN, Ethernet (TCP/IP and UDP), ARINC429, SYNC-I/Os
  • Data output rate up to 500 Hz (each data log separately adjustable)
  • Integrated all-frequencies / all-constellations GNSS Receiver with RTK capability and dual-antenna heading support.
  • Interface to external wheel sensor to provide also full dead reckoning operation
  • Gyro compassing capability (determines true north without any need of GNSS)
  • Inertial Sensor and System Performance: see datasheet
  • Integrated 42+ state EKF based sensor data fusion
  • Internally up to 128 GByte non-volatile memory for data storage
  • Connectors: MIL-C-38999 III type and TNC
  • Power Supply: 10...34 V DC, < 25 W
  • Weight: approx. 5.5 kg
  • Power supply and EMI-EMC protection qualified to MIL-STD-704F / MIL-STD-461G / MIL-STD-810G; partially designed to meet DO160G
  • Modular system architecture: customized applications can be integrated by iMAR easily (please contact our sales for details). So the iCOMBANA can provide arbitrary data and command protocols according to customer requirement, e.g. to substitute other navigation systems by iCOMBANA (e.g. for Form-Fit-Function replacements)
  • integrated all-frequencies / all-constellation GNSS engine; interface to external mil grade GNSS receivers (SAASM, M-Code etc.) like ERGR, NavHub, TopStar
  • iCOMBANA is not subject to any ITAR control


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.

Several classes of iCOMBANA are available (here sorted by increasing accuracy):
