Ellipse 2 Micro Series: an industrial quality micro-sensor

SBG Systems designed its Ellipse 2 Micro Series range with the aim of providing users with a new and even more compact navigation system (less than 2.7 cm long for just 10 g) without compromising on efficiency and performance. The Ellipse 2 Micro Series offers 3 models:

  • A 9-axis inertial measurement unit (Ellipse 2 Micro IMU)
  • An altitude and heading reference system with an extended Kalman filter
  • An inertial navigation system with all the functionalities of the previous models and an additional connection to a GNSS receiver and odometer

In the version shown here, SBG Systems brings users a precise, stable, long-lasting and economical navigation system. Its small size means it can be integrated into all kinds of projects requiring an on-board IMU: autonomous land vehicles, gimbal cameras, automated surveillance systems, drones, etc.

A complete development kit for your IMU

The SBG Systems IMU comes with an evaluation board that can adapt to each of the 3 models in the Ellipse 2 Micro Series. All programming takes place using sbgCenter, a Windows-based software allowing you to not only visualise the data transmitted by the IMU in real time, but also:

  • quickly configure the unit and analyse data over time
  • export this data to Excel, Matlab or Google Earth

The IMU comes with a C library, so you can further broaden your experience by playing with some source code examples.
