ESSB-HB-E-003, ESA POINTING ERROR ENGINEERING HANDBOOK (19-JUL-2011)

ESSB-HB-E-003, ESA POINTING ERROR ENGINEERING HANDBOOK (19-JUL-2011)., The ECSS Control Performance standard E-ST-60-10C, ECSS-E-ST-60-10C, provides solid and exact elements to build up a performance error budget. However, the elements recommended are not embedded in an engineering framework and thus an intermediate document developing a Pointing Error Engineering (PEE) methodology is herewith formulated, as foreseen in Note 3 of ECSS-E-ST-60-10C: ‚For their own specific purpose, each entity (ESA, national agencies, primes) can further elaborate internal documents, deriving appropriate guidelines and summation rules based on the top level clauses gathered in this E-ST-60-10C standard.‛ The purpose of this handbook is to be used by ESA projects as reference document providing clauses, guidelines, recommendations and examples, consistent with and elaborating the E-ST-60-10C for the specific case of satellite pointing errors. This handbook provides * guidelines for characterization of pointing error sources, * guidelines for analysing pointing error source contribution to the actual pointing error index, * summation and compilation guidelines for the system pointing error budget. Specific and quantitative performance pointing requirements are expressed as usual in the ESA Mission Requirement Document and System Requirement Document, and further broken down and engineered by the prime contractor in the various project phases.
