Summary This research seeks to better understand the conditions under which undersea terrain aided navigation (TAN) will succeed. Undersea TAN is the process of correlating sonar or photographic sensor measurements with a pre-existing bathymetry map to provide position estimates to the underwater vehicle. This technique permits an Autonomous Underwater Vehicle (AUV) to navigate accurately without using GPS. For TAN to succeed it is dependent of several factors including the rugosity of the terrain, sensor selection, position estimation, route planning and system uncertainty. Through thorough analysis and simulation the research goal seeks to provide recommendations to permit quality TAN performance.
