The Underwater Positioning System (UPS) is designed to determine the position of a vessel operating at a dedicated testing ground or an Underwater Object (UO) fitted with a Mobile Responder Beacon (MRB)
Device appearance
Stationary Bottom Responder Beacon
Objectives
Locating and tracking of underwater object position using the Ultra-Short Baseline (USBL) method
Locating and tracking of underwater object position within a dedicated testing ground using the Long Baseline (LBL) method
Locating and tracking of vessel position within at a dedicated testing ground using the LBL method
System structure
Shipborne components;acoustic antenna, retractable deployment system, equipment cabinets with transmitting/receiving equipment, operator workstation, and control device (unit 40) for MRB deployment
