The report describes recent activities and results in a program to develop a general-purpose ocean data station buoy and associated shore-based mobile data facilities to be used to acquire oceanographic and meteorological data in scientific experiments at sea. The telemetry and command single-sideband radio equipment being installed in the buoys is capable of operating over distances of at least 2,500 miles 4,022 km using ordinary ionospheric short-wave propagation, but makes use of the most recent techniques in information encoding to use radio spectrum bandwidth most efficiently and effectively. The experimental operation of prototype BRAVO is covered. The report describes the Mobile Data Center being prepared for use with the prototypes, permitting long range interrogation of the buoy and reception of environmental data acquired by the buoy. Subsystem tests and results are reported, including developmental testing of the anti-collision light and the electric power system. In the case of the electric power system, important new information concerning the extended duration performance characteristics of nickel-cadmium storage batteries is presented. Reliability and performance of a considerable number of commercially available meteorological sensors tested at sea on prototype BRAVO is also reported. Author
