Major Firmware Update for Ellipse Sensors

Firmware Update – Ellipse & Ellipse Micro

SBG Systems announces a major firmware update for the Ellipse product line. New exciting features were added to this new version 1.7, all designed to enhance the sensor performance.

Automotive Package

New features were developed in order to better answer the autonomous testing and driving markets. These features include:

• CAN odometer: You have now the choice to connect an external odometer (DMI) with pulses or use your car odometer with velocity information.  During the installation, you can enter a rough “resolution”. Then, SBG’s inertial sensor refines the odometer installation parameters to automatically obtain the best performance.
• New outputs: body velocity and slip angle, which calculates the “drift” angle between the vehicle assumed trajectory and its actual (deviated) trajectory.

Fixed lever arms mode

For precision applications as well as low dynamics, and reduced warmup time, the new Ellipse INS sensors firmware allows to run the Ellipse Kalman filter with no lever arm estimation. This will ensure centimeter pass to pass accuracy for RTK applications and allow operation in lower dynamics while reducing the warm-up time.

In order to precisely calibrate the lever arms, the use of Qinertia Lite can be used to obtain centimeter precise lever arms. For general purpose applications, the standard mode of operation, that refines the lever arms in real time is still available.

Marine applications improvements

This Ellipse INS sensors firmware provides new features for advanced marine applications.

• DVL aiding support helps to reduce drifts from the inertial sensor underwater. An interesting opportunity for projects including short subsea navigation with affordable inertial sensors.
• New output message (INDYN) brings support to performance sailing autopilots such as B&G H5000.

Improved magnetic calibration (sbgCenter)

The new sbgCenter embeds a new magnetic calibration algorithm that improved overall performance in challenging calibration, while allowing even more difficult calibration conditions. This new calibration procedure also provides improved quality feedback.
