A Buoy Transmit Terminal for the Nimbus-F Satellite

The overall Buoy Transmit Terminal (BTT) to Nimbus-F Satellite, RAMS (Random Access Measurement System) concept is examined. This system provides a dual position fixing and communication function. A general approach to meeting the BTT requirements is discussed. The paper continues with a discussion of the development of the various BTT elements which make it ideally suited for placement on-board buoys with small payloads. Sample performance parameters, derived from test data, are presented to provide a measure of familiarity with the BTT and its applications.
