DEFINITION
  • An autonomous underwater vehicle (AUV) based on buoyancy. It was developed for continuous, long-term measurement of oceanographic parameters. It uses small changes in buoyancy and wings to achieve forward motion. The system's pitch and roll are controlled using adjustable ballast (the vehicle battery). The vehicle moves through the water in a saw-tooth like pattern and surfaces often to determine its position. Navigation is accomplished using a combination of GPS fixes while on the surface and internal sensors that monitor the vehicle heading, depth and attitude during dives. External sensors are constantly scanning the ocean to determine environmental properties. The glider is 1.8 - 2 m long with a maximum diameter of 30 cm and antenna mast length between 43 cm and 1 m. It weighs 52 kg with a wing span of 1 m. It has a deployment range of 4600 km, deployment length of 10 months and an operating depth range between 50-1000 m. Maximum speed is 25 cm/s.
