The SAMPEX Data Processing Unit
Abstract
The paper discusses salient features of the SAMPEX Data Processing Unit (DPU), the primary function of which is to collect sensor data to create telemetry packets for transmission to the solid-state recorder located within the Small Explorer Data System. Particular attention is given to the sensor interface electronics, the space command interface, the spacecraft telemetry interface, and the memory mapper of the DPU system; the task scheduling concept; and system reconfiguring. A block diagram of the DPU system is included.
