This proposal is the DTU response to the Dornier DSS (DSS) request for proposal (r.f.p.) for the ROCSAT-2 star tracker.ROCSAT-2 is jointly developed by DSS with the taiwanese Space Agency (NSPO) and consists mainly of an optical camera as well as a customer furnished scientific instrument. ROCSAT-2 System Integration is supposed to take place at NSPO facilities.The ASC is a highly advanced and autonomous Stellar Reference Unit designed, developed and produced by the Space Instrumentation Group of the Department of Automation of the Technical University of Denmark.The document is structured as follows. First we present the ASC - heritage, system description, performance - then we address more specifically the environmental properties, like the EMC compatibility and thermal characteristics, and the design and reliability issues. Section 6 deals with the testing and the calibration procedures and in section 7 the mechanical and electrical interfaces are given. In section 8 and 9 we address issues like manufacturing, transportation and storage and to conclude in section 10 the requirements imposed by the ASC on the system are given.
