- The Most Advanced Miniature Inertial Sensors

Ellipse inertial sensors provide outstanding orientation and position data in a small, light-weight, and rugged enclosure. Incredibly versatile, you can connect your own GPS or use the internal one, connect an odometer, receive differential GPS corrections, etc.

A little larger, the amazing Ellipse-D completes this state-of-the-art product line. It integrates a Survey-grade L1/L2 GNSS receiver with two antennas for unmatched heading and posi-tion accuracy.

Pressure Sensor

The advanced FIR filters coupled with Coning & Sculling integrals provide efficient vibration rejection, while an Extended Kalman filter fuses inertial data with GNSS, or other aiding information.

An exclusive anti-jamming technology is also used to reject bad/false GPS measurements.

Every sensor is intensively tested and calibrated from -40 to 85°C for a robust performance in all conditions.

The magnetic calibration tool allows easy soft and hard magnetic disturbances compensation. A library is provided for a quick integration into your application.

Motion Profiles allow you to deeply tune your sensor to your application constraints.

Select a Motion Profile, and para-meters will automatically adjust to Kalman Filter, vibration level, dynamics, magnetic disturbance immunity, etc.
