The 2.x firmware introduces support for new ELLIPSE Series 3 hardware. It brings many performance improvements by taking advantage of a more powerful 64 bit CPU allowing double precision computations and more complex algorithms.

A lot of code has been reworked to improve the overall quality, stability, reliability of the sensor and especially regarding how the time is managed.

The main new features and additions are listed below:

  • Adds support for new ELLIPSE Series 3 hardware
  • Improved accuracy and performance with an updated Extended Kalman Filter using double precision numbers for all operations for ELLIPSE Series 3 hardware. This also improve the filter stability and reliability in difficult conditions and during low dynamics.
  • This firmware includes the latest World Magnetic Model to cover the 2020 to 2025 time frame
  • Improved UTC and PPS time management to better cop with noisy PPS signals

Firmware Download

You can download the ELLIPSE firmware package compatible with ELLIPSE v3.

Please use the sbgFirmwareUpdater tool to update your device firmware and refer to the the firmware upgrade procedure for a step-by-step guide.
