2. INTRODUCTION
AUVs are Autonomous Underwater Vehicles that are used
to perform underwater survey missions.
It is a robotic device that is driven through water by
propulsion system, controlled and piloted by an onboard
computer.
Other type of UUV includes Remotely operated
underwater vehicles(ROVs) controlled and powered from
the surface by an operator.

5. FUNCTIONS OF AUV

6. NAVIGATION
 GPS receivers to measure position at the surface.
 Underwater acoustic positioning system-
Long base line transponders to measure the
distance from the AUV to transponders in the
known locations.

7. SONAR SCANNING
Sonar is a technique that uses sound propagation
to navigate , communicate with or detect other
vessels.

8. APPLICATIONS
 Oceanography
 Oil and Gas industry
 Mine countermeasures
 Anti submarine warfare
 Air crash investigations
 Geological survey

9. ADVANTAGES
 Long term economic benefits owing to dramatic
improvement of data quality
 Operate free of any tether cables
 Deployed in missions that pose a risk to human
life
 Able to harbour multiple system at the same time
