Abstract:Autonomous underwater glider (AUG) is one kind of UUVs under development. Its application as probe in the sea is an issue of technical method. Aiming at the future environment detection AUG with heavy load, based on analysis of sea envi- ronment, target and AUG technical characteristics, the future application and test method is discussed, application methods of area route navigation, target orediction zone, stealth detection, satellite communication based on sea and target environment are studied, and the typical status testing method is simulated and analyzed,which has reference to relative testing researches.
