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.
