Racing Ships

Compact and Reliable INS for Racing Ship Motion Monitoring and Navigation

Getting motion information is especially important for dynamics analysis to build the most efficient ship, and for safety to avoid capsizing.

The GNSS-aided AHRS also provides precise and robust real-time navigation data.

Tips

Two antennas will provide a more precise heading, especially when the ship is in slow motion and a lot faster initialization. At least two constellations are recommended to optimize satellite availability, so a more robust heading.

More information ››

Antennas should be installed in a spot where the GNSS reception is optimal such as the back of the boat. It should be installed far from obstacles like the sailing boom for example.

If you want to pair the Ellipse2-E with your own GNSS receiver, note that we recommend using a survey grade GNSS receiver for robust navigation.
