Preliminary Results from a GPS-based Portable lmpact Location Svstem

Jimmy Saunders and Miguel Cardoza

Abstract:	Applied Research Laboratories, The University of Texas at Austin (ARL:UT), has developed a prototype portable impact location system which utilizes air deployed, GPS equipped sonobuoys to localize the acoustic energy released when a projectile impacts the ocean. Meter level impact localization is realized using a low-cost OEM sensor, and DGPS realtime and postprocessing software. This paper reviews the operational concept and development constraints of the portable impact location system, and describes the selection, testing, and integration of a low-cost disposable OEM sensor into an air deployable sonobuoy. In addition, data reduction software developed to optimize DGPS positioning accuracy is discussed, along with preliminary performance results from open ocean demonstration tests.
