Abstract:	The use of precisely positioned sonobuoys for military and civilian applications such as anti- submarine warfare (ASW) and search and rescue missions are summarized. The use of low cost GPS receiver technology to resolve the positioning problem is assessed through a series of marine trials conducted by DND/DREA between January and October 95. During these trials, sonobuoys were deployed from a ship and positioned relative to the ship using DGPS. The DGPS data collected during the January 95 trial off the coast of Bermuda was analyzed in post-mission mode. During the October 1995 trial, conducted off the coast of Nova Scotia, DGPS was used in real-time. Low cost Rockwell MicroTracker receivers were used on the sonobuoys while NovAtel Model 951 units were used on ship. The data analyses presented herein show that a relative DRMS accuracy of about 3 m, which is sufficient for most applications, was obtained during both the trials.
