| Definition | An autonomous underwater vehicle (AUV) based on buoyancy, developed at the University of Washington for continuous, long-term measurement of oceanographic parameters at full ocean depth. It uses small changes in buoyancy and wings to achieve forward motion. The systems pitch and roll are controlled using adjustable ballast (the vehicle battery). Pitch and roll trim are automatic. The vehicle moves through the water in a saw-tooth like pattern and surfaces often to determine its position. Navigation is waypoint-based and accomplished using a combination of GPS fixes while on the surface and internal sensors that monitor the vehicle heading, depth and attitude during dives. The SGX features advanced navigation capabilities including under-ice behaviour. External sensors are constantly scanning the ocean to determine environmental properties. The glider is approximately 203 cm long with a maximum diameter of 29.5 cm. It has a nominal displacement of 70 kg and is rated to 1000 m depth. The nominal mission duration for SGX is 12 months with continuous sampling, which may be extended with periods of loitering. Maximum roll is 80 degrees. Typical speeds of 0.1 - 0.25 m/s horizontal, 0.1 m/s vertical. | |
