Eagle Ray AUV
The Eagle Ray AUV is designed for deepwater operation to 2200 meters. Its ~5 meter length provides payload volume for mission-specific sensors, as well as the primary multibeam sonar and conductivity-temperature-density (CTD) sensor. Surveys greater than 150 km long and deployments over 36 hours in duration can be achieved.
The vehicle navigates using Doppler velocity log-aided inertial guidance. Acoustic communications provide continuous system status and allow limited operator influence on mission parameters. An independent acoustic tracking system monitors the vehicle’s position at all times.
A 200 kHz multibeam sonar generates seafloor images from an altitude of 50 meters providing significantly higher resolution bathymetry than can be achieved from ship-mounted systems.
