AbstractAdvanced sonobuoy systems, targeted for the MMA platform, require to be dynamically programmed by flight line technicians and platform computer operators. Current Sonobuoy systems are programmed with mission parameter data (RF channel, depth, and life) via a mechanical push button switch panel and verified on a red two-digit LED display. Once installed into the launcher, buoy parameters can not be altered while in flight in response to a change in mission profile. Additionally, the process of manual data entry on a large number of sonobuoys is prone to operator error, often not discovered until sonobuoy deployment. Navmar has developed and demonstrated an optical Remote Electronic Function Select concept (REFS) and system. The prototyped hardware demonstrated operator remote programming of a REFS equipped sonobuoy test component, utilizing the IR optical linking feature of a COTS Communications component coupled with a terminal controller embodied in a Palm IIIxe PDA. The REFS design has also addressed the requirement that buoys be programmed while housed in related MMA sonobuoy sub-systems by demonstrating an optical communication link of a REFS sonobuoy to a simulated launcher component. Overall, the Remote Electronic Function Select system can be applied to a variety of components including miniature sonobuoys.
