The 1.9 firmware series is a major update that adds several important new features, performance improvements and bug fixes.
The main new features and additions are listed below:
Updated World Magnetic Model to cover the 2020 to 2025 time frame
Up to now, ELLIPSE INS was continuously estimating and refining mechanical installation parameters such as GNSS primary and secondary lever arm antennas. Even if this behavior is great for ease of use, with the 1.7 release, it’s now possible to select the best behavior according to your use case and stop online lever arm estimation.
This can reduce the alignment time while improving the accuracy and stability of the system.
If you can’t measure precisely the lever arm (<2 cm) , you can use Qinertia to do it automatically
To better address the automotive market, the ELLIPSE can now output, over the CAN bus, several new quantities such as the velocity expressed in the vehicle frame (body), the slip angle as well as the curvature (turn radius).
Now, the ELLIPSE is also able to use vehicle’s odometer directly through the OBDII connector. This makes the ELLIPSE an outstanding INS for self driving cars and autonomous vehicles with incredible accuracy even in very dense urban environments.
Doppler Velocity Log (DVL) aiding has also been added to the ELLIPSE to enable INS grade subsea navigation at a very affordable price.
Finally, preparatory work has been done to fully support air data aiding. This new aiding source aims to improve ELLIPSE attitude and dead reckoning accuracy in case of GNSS drop out. The ELLIPSE is now able to receive and process external true air speed and barometric altitude. This a work in progress feature so please contact SBG Systems support team for more information
