The data processing unit within the framework of the Intershock project is a general-purpose computer modified to be installed onboard the satellite. The instrument inputs have analog digital and impulse sensors. it generates digital arrays to be stored in a
long-time memory (LTM). The data processing unit´s operations are functionally determined by programs stored in the processor memory. In this specific case the instrument is intended for a comprehensive study of the structure of shock waves in the space plasma. The instrument has a reprogramming system which can make onflight changes in the instrument´s scheduled operations so that the instrument can solve a different problem which conforms with the instrument capabilities and the software used.
The paper describes the tasks, technical means and methods of information express analysis as well as experiment control in the stage of its implementation, including BROD reprogramming.
