Pointing Error Engineering Software Framework

The main objective of this activity is to develop, enhance and maintain a software framework supporting Satellite Pointing Error Engineering for all ESA missions, in line with the ECSS Control Performance Standard ECSS E-60-10C which does not authorise the traditional simplified summation rules.  

The activity will develop a first version of the software framework based on the experience got through a successful prototyping exercise in 2012 called PEET (Pointing Error Engineering Tool). The prototype implements the step-by-step process elaborated in the ESA Pointing Error Engineering Handbook published in 2011 as ESA applicable document ESSB-HB-E-003.An accompanying SW framework is necessary to process complex calculations for high accuracy pointing, to support frequency domain techniques introduced in thehandbook and to provide traceability and a common platform for exchange ofinformation between the various entities.In particular, the following tasks are foreseen:Review of lessons learnt from the prototype and feedback from users.Update of the software framework requirements.Review and streamlining of the core computational routines of the PEET prototype to optimise SW execution.Extension of modules to support high precisions missions (e.g. Euclid, MTG,EDRS,etc).Based on the existing sensitivity analysis feature, implementation of a specific functionality for pointing requirement allocation (apportionment).Extension of the reporting functionality according to suggestions by future users in ESA and industry.Extension of the PEET website with repository, bug tracker, online manual, tutorial and forum.
