AbstractVME bus has been widely accepted as an industry standard for control and process computers. The MSTI (Miniature Sensor Technology Integration) series of satellites employ a VME bus based data acquisition and control system. This system requires a ruggedized, high-speed, compact, low power and light weight data recorder for storing digital imagery from payload video cameras, as well as health and status data of the satellite. No commercial off the shelf systems were found which meet MSTI specifications. Also, a solid state device eliminates certain reliability and spacecraft pointing control problems which are encountered when using rotating (disk or tape) storage systems. The SSDR was designed to meet these requirements and it also has built-in flexibility for many general purpose applications. The electronic hardware design, which conforms to the VME bus specifications , can also be configured as stand-alone system. Modular memory array design allows expandability of capacity up to 320 MBytes. This paper will describe the design features of the SSDR. Performance capabilities and system implementation will be discussed. Special approaches required for application of the SSDR in space or harsh environments are also discussed.
