Framework definition and prototyping for the coordinated development and validation of AOCS units simulation models by AOCS unit suppliers. The generic development of such Building Blocks has been recommended by the ESA avionics workshop ADCSS in 2007 and the associated bilaterals with industry.

An experienced AOCS contractor shall develop the generic requirements and framework for AOCS units modelling and together with some unit supplier(s) develop a first set of simulation models. The initiative will consider both functional models of adequate fidelity needed for AOCS system design, and interface-representative models for avionics verification on Virtual Test Bench. This contract should be followed by dedicated model developments with each unit supplier to produce and validate, against real unit tests, the models for their units. These models shall be made available to all European companies as part of unit procurement.
