The system for scientific payload information support (SIOK) has been designed for controlling scientific instrumentation operation of the "Phobos-Grunt" mission s/c. This is dual computer with an extended nonvolative memory.

SIOK will provide for following task solution:
  reception of onboard commands and onboard time code from the s/c housekeeping systems via the SIOK–s/c data line;
  digital command transmission передачу цифровых команд для управления научными приборами и кода бортового времени по внутренней информационной магистрали связи СИОК и научных приборов;
  collection and storage in permanent memory of data? aquired by the s/c scientific payload;
  scientific data translation from memory to s/c radio system during communications sessions.
