Exercise Torpedo End-Of-Run (EOR) Global Positioning System (GPS) Locator

The US Navy seeks the development of a miniature transponder locator unit, capable of sustaining high shock loads that can be placed in both lightweight and heavyweight exercise torpedoes for rapid torpedo recovery. Currently, a considerable amount of time and resources is expended to visually search for the exercise torpedo after the end of run, and the solicitation aims to develop a system that enables timely recovery of the exercise torpedo with limited assets. The transponder must have an endurance of 24 hours, determine the torpedo"s location via a GPS receiver, and communicate the torpedo"s position via an RF and underwater acoustic link at ranges up to 5 nautical miles. In this Phase II proposal, Adaptive Methods proposes to design and fabricate an EDM and Limited Run Initial Production (LRIP) units that meet all solicitation requirements including weight, volume, HERO, SUBSAFE, and communications ranges. During this work we will perform an in-water demonstration showing that the system meets all requirements, and also support US Navy testing with LRIP units.
