Study of Design Methodologies for Digital Attitude Control System Algorithms. Volume 3: New Illustrative Concept Satellite (NICS), a Case Study in Attitude Control Subsystems (ADCS) Software Procurement

摘要

The mission and AOCS of NICS are outlined, and the phase B and phase C/D documentation are presented. Phase B documents include the preliminary software requirements specification, giving the AOCS functional requirements for implementation as AOCS computer program, the software architectural design, which comprises operating system, AOCS application software and timing aspects, and interface control documents. Phase C/D documents include a specification change from four gyros to six, the software requirements specification in which AOCS functions and algorithms are defined, unit specifications, the computer program component specifications, and a listing.
