AbstractThis paper discusses the design concepts of a central data system (CDS) for more efficient" flexible data management and its application in an advanced deep space solar probe. The design features high data sampling rates, programmable data processing, bulk data storage capability (for data sampled during periods of noncommunication), and standard experiment package/CDS interfaces. The basic system concept is based upon sampling each data point at a high rate in a fixed sequence and allowing a central processor to select, process, and format sampled data into a highly efficient format for transmission. The CDS is programmable so that data formatting and processing may be reprogrammed via the command link to optimize data transmission for unexpected conditions. Preliminary design efforts have indicated that a CDS to process data from seven particle and fields experiments can be designed, using present state-of-the-art components, to weigh 16.5 lb and consume 5.4 watts (not including bulk data storage unit) from the DC/DC converter.
