  Developing OBDH for satellite should consider the condition of the existing
research facilities and resources in an institution. Many OBDH developments
have been failed because not considering the capabilities of the institution.
Considering to the capabilities of the institution is important, because it is
major factor whether building OBDH can be realized successfully or not.
  System Design OBDH that has great opportunities to success in our research
environment is to concentrate on developing the software for the OBDH. The
software must be supported with the appropriate hardware which has been
recognized as space qualified. Therefore selection board which has space
qualified is important method: it has been conducted in this research. To
develop good software in the term of perspective programming, fast,
standardize, testable, multitasking: Operating System has been implemented in
this OBDH.
  This research showed the OBDH development is pretty fast and more realizable
to the limited institution resources. This research has produced an OBDH
prototype in terms of hardware/board selection and software development.
