  • Specifications


Ellipse-N is a light-weight sensor which includes a MEMS-based Inertial Measurement Unit (IMU) integrating three gyroscopes, three accelerometers, and three magnetometers. It runs an enhanced Extended Kalman Filter (EKF) which fuses inertial data with GNSS, Odometer, and DGPS information for excellent orientation and navigation data in the most challenging environments.

Available configurations:



All-in-one Powerful INS/GNSS

Ellipse-N is a full-featured miniature inertial navigation sensor. It embeds the latest generation of GNSS receivers (GPS + GLONASS or GPS + BEIDOU) for a better satellite availability in harsh GPS environments (i.e urban canyons). In addition to provide accurate position and velocity, the GPS aiding allows the Ellipse-N to maintain accurate orientation even during long term accelerations. This advanced inertial sensor additionally accepts differential corrections for even more precise navigation data.



  • Marine: For such a compact and cost-effective sensor, Ellipse-N features an advanced heave capability which automatically adjusts to the wave period. Ellipse-N is water-resistant (IP68) and is perfectly suited to marine applications such as Unmanned Marine Vehicle (UMV) orientation and navigation, Buoy or Racing Boat Motion Monitoring, etc.
  • Land: Additionally to embedding a GNSS receiver and accepting differential corrections, Ellipse-N can be connected to an odometer for a smooth trajectory in urban canyons, tunnels, and forest. Ellipse-N is perfectly fitted to Car Motion Analysis or Unmanned Ground Vehicle (UGV) navigation for example.
  • Aerospace: The internal GNSS receiver combined with DGPS corrections makes the Ellipse-N the ideal solution for aerospace applications where high performance is needed in a compact sensor such as Avionics or UAV Navigation. Temperature calibrated, the Ellipse-N provides reliable attitude and positioning data even during temperature variations.


OEM Version

This lighter version of the Ellipse-N will benefit to designers who are searching for high performance in a light-weight (12 grams) and compact package.

This OEM version is more robust and easier to integrate than traditional PCB boards OEM modules.
