Sonobuoy constitutes a key sensory component in modern anti-submarine warfare (ASW) by performing crucial tasks such as reconnaissance under water using sonar. In order to obtain accurate information about the location of possible submarines, it is necessary to know the position of these sonobuoys at all times. However, in GPS-denied situations, alternate methods are necessary to localize the sonobuoys for extended periods of time on the scale of 8-12 hrs at a stretch. As TDOA/AOA based approaches provide fairly large positioning error, IAI propose to investigate RF ranging techniques for sonobuoy positioning system in conjunction with buoy drift model analysis.
