ECSS-E-ST-10-09C, SPACE ENGINEERING: REFERENCE COORDINATE SYSTEM (31-JUL-2008)

ECSS-E-ST-10-09C, SPACE ENGINEERING: REFERENCE COORDINATE SYSTEM (31-JUL-2008)., Clear definition of reference directions, coordinate systems and their inter‐relationships is part of the System Engineering process. Problems caused by inadequate early definition, often pass unnoticed during the exchange of technical information. This Standard addresses this by separating the technical aspects from the issues connected with process, maintenance and transfer of such information. Clause 4 provides some explanation and justification, applicable to all types of space systems, missions and phases. Clause 5 contains the requirements and recommendations. Helpful and informative material is provided in the Annexes.
