Racing Ships
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.
Recommended products
Dual antenna GNSS/INS
Motion Sensor
Ellipse-D is a compact Inertial Navigation System with integrated Dual antenna RTK GNSS receiver for precise position and heading. It provides Roll, Pitch, Heading, Heave and Navigation data.
Ellipse-E
Externally-aided INS
Ellipse-E is a small-sized high performance Inertial Navigation System. It provides Roll, Pitch, Heading, and Heave, and computes Navigation data when connected to an external GNSS receiver.
Ellipse-A
Motion Only
This light-weight sensor (45 grams) is a small-sized high performance Attitude and Heading Reference System (AHRS). It provides Roll, Pitch, Heading, and Heave data that adjust to the wave frequency.
Case studies
Wave buoys in the Arctic Sea ice
Marginal Ice Zone (MIZ) Program Over recent decades the Arctic has warmed more than any other region leading to significant reduction in sea ice volume. The combination of increased ice-free area and more mobile ice cover has led to the emergence of a seasonal marginal ice zone (MIZ) in the Beaufort Sea. The Office of … Continued

Tips
One or Two Antennas for Accurate Heading?
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.
Where to Install the Antennas?
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.
High-end GNSS Receivers
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.
