THE DEVELOPMENT OF CDH SUBSYSTEM IN THE D-SAT SYSTEM

摘要

This paper demonstrates the in-house development of the subsystem C&DH in a D-SAT satelliternproject of Astronautic Technology (M) Sdn. Bhd. (ATSB). D-SAT is a non-imaging satellite. It will carry a dosimeter as the payload for scientific objectives. Since one of the D-SAT project establishment intended objectives is to demonstrate the research and development skill of the ATSB engineers on the satellite system building, most of the subsystems of the D-SAT are de-veloped in-house including the C&DH subsystem. C&DH subsystem plays an important role for managing data handling tasks and general operation of the satellite system. The C&DH devel-opmentrnincludes the research and study on the hardware and software design, the design of bothrnthe hardware and software, the development of the software system, the integration between thernsoftware and the hardware system and the implementation of the subsystem into the satelliternsystem. This program allows ATSB to accomplish the engineers with expertise not only in thernC&DH subsystem but other subsystems too besides developing knowledge in the managementrnof a space project that covers not only on the technical issues but issues relating to the eco-nomic, political and legal issues.
