USV – Unmanned Sea Vehicles
Compact Inertial Navigation Systems for Unmanned Surface Vessel
An all-in-one INS with a dual antenna GNSS receiver delivers a centimeter-level position (RTK) as well as roll, pitch, and heading. The INS additionally provides accurate heave data, automatically adjusted to the wave period.
It is suited for USV navigation when GNSS outages occur, and for precise payload stabilization such as echo-sounders.

Tips
Be careful to select the model that is the best suited for the navigation accuracy required by your payload. For example, an Ellipse2-D integrates a bi-frequency GNSS receiver allowing centimetric-level RTK, an Apogee-D integrates a tri-frequency GNSS receiver which gives additional access to Precise Point Positioning (Terrastar, Omnistar, etc.).
Compared to a Motion Reference Unit (MRU), the Inertial Navigation Systems (INS) greatly improves navigation data in all conditions. Position information are fused in real-time with inertial data to provide a robust trajectory when GNSS outages occur (crossing a bridge, surveying a river near several mountains, etc.).
A dual antenna receiver delivers a more precise GNSS-based heading in marine applications. Highly accurate heading is required for high precision payloads, such as multibeam echo-sounders, when the quality of the generated point cloud depends on it.
