Abstract
An initial evaluation of an acoustic telemetry link between an Aurora patrol aircraft and CFAV QUEST is documented. The link was designed to transmit continuous, real-time acoustic data from sixteen DIFAR sonobuoys between the Aurora and the QUEST. In two recent trials of the acoustic telemetry link system, reliable transmission was obtained out to ranges of fifty nautical miles with a tracking antenna receiving system and to ranges of seven nautical miles with an omnidirectional antenna. In each case, the aircraft was required to fly a dedicated pattern to maintain the link and there were short periods during each pattern that the link was poor due to transmission shadows cast by the aircraft or the ship. The report contains a detailed description of the acoustic telemetry link system as well as an initial evaluation of the operating envelopes currently imposed on the Aurora and the QUEST in order to maintain reliable transmission. In addition, recommendations for improving the quality and flexibility of the link are made in the concluding section.
