High Accuracy Inertial Sensors


0.05° – Ekinox takes MEMS to the next level.

R&D specialists usually compromise between high accuracy and price. The ITAR Free Ekinox Series has been designed to take robust and cost-effective MEMS to the Tactical Grade. Compromise is no longer required between high accuracy & cost.

Miniature Inertial Sensors

Our miniature Inertial Systems provide an accurate 3d orientation and also, for certain products, a precise 3d position. Each Inertial System uses a set of 3D gyroscopes, accelerometers and magnetometers to track, in real time, every movement. This allows an accurate orientation measurement even in severe dynamic conditions.

All our sensors are calibrated over their full temperature range and compensated for misalignment, cross-axis and other effects such as Gyro-G effect, making them ideal for demanding applications.

  • Roll, Pitch:                          Up to 0.35°
  • Heading:                             Up to 0.5°
  • Position:                             2 m ( GPS)
  • Heave:                                10 cm
  • Aiding equipment:           GNSS, Odometer.

NEW Ellipse Series – More Accurate, More Robust, More Versatile

Ellipse Series is a brand new product family of miniature inertial sensors. Ellipse Series is more accurate, more robust, and more versatile than the original IG-500 Series - for the same budget. In addition, Ellipse Series comes with features inspired from high end inertial systems such as FIR and anti-rejection filtering, robust IP68 enclosure, high output rate, RTK corrections, automatic alignment, etc.
