Description
In the coming decade, we can expect to see an expansion in the utilization of space vehicles for the benefit of society. System design studies for resource measurement and management, meteorology, oceanography, mapping and indeed in all areas where space technology can provide a cost effective means of gathering data on a global scale are in progress now. In the first part of the paper, the resulting growth in requirements for data storage on spacecraft is discussed, as well as the technology at hand for storing required data in the most appropriate form and at suitable input and output rates. It also suggests the most economical means of storing data in spacecraft.
The second part of the paper will discuss the servo-driven tape recorder approach to meeting these requirements. It is shown that, by use of the servo approach, a very flexible and simple mechanical design can be employed having only eight rotating parts. An analysis of the servo loop response is presented and it is shown what system parameters are important in obtaining minimum flutter.
The last part of the paper is concerned with processing the data before and after recording. Equalization needs for FM and digital data systems are discussed. In addition, the computer aided design approach to the analog and digital data channels of the High Data Rate Storage System for the Nimbus B and D meteorological satellite is described.
