Ellipse2-E: Miniature INS

Ellipse2-E is a small-sized high performance Inertial Navigation System. It provides Roll, Pitch, Heading, and Heave, and computes Navigation data when connected to an external GNSS receiver. It accepts Odometer aiding to maintain the best accuracy in challenging environments.



This light-weight sensor (49 grams) includes a MEMS-based Inertial Measurement Unit (IMU) and runs an enhanced Extended Kalman Filter (EKF) which fuses inertial and aiding information to provide accurate real time orientation and navigation data.

High Accuracy for Such a Small Sensor:

  • 0.1° Roll and Pitch over 360°
  • 0.5° Heading (When connected to GPS)
  • 5 cm Real-time Heave, adjusted to the wave period
  • Position accuracy depends on the external GNSS

Key Features:

  • Very Low Noise Gyroscopes, High Quality Accelerometers
  • Connection to external GNSS and Odometer (DMI)
  • IP 68 Enclosure
  • 200 Hz Output Rate
  • 2 years warranty

Connect to a GNSS receiver and an Odometer for a Smooth Trajectory

Ellipse2-E is incredibly versatile. You can use your own GNSS receiver for Navigation data. The internal Kalman Filter will fuse in real-time inertial and GNSS data for enhanced position and orientation measurements. For Land applications, the Ellipse2-E becomes a powerful dead reckoning solution when connected to an odometer.
