A lot of researches are being conducted underwater. Exploring an unknown place can become tricking especially when navigation becomes 3 dimensional compared to land navigation where a 2 dimensional plot is enough. GPS does work underwater and therefore, sound waves are being used to obtain information of the surroundings underwater. GPS can measure the distance between the object to be tracked and a base station, in this case, a buoy. The buoy will then be used to track an AUV underwater using sonar. Sonar works by using sound waves as a mean of detection. It can be used by emitting pulses of sound and detecting the echoes. This report is a study of how the GPS works, how sonar works and also to create a program to track the position of an Autonomous Underwater Vehicle (AUV). This will be simulated using matlab.
