***PLEASE NOTE THE CLOSING DATE FOR THIS REQUIREMENT IS 13/04/2017 AT 14:00PM, PLEASE DO NOT APPLY DIRECT TO THE BUYER*** The Science and Technology Facilities Council (STFC) department of RAL Space is designing and building five blackbody targets for the calibration of two instruments on the European Space Agency (ESA) Meteosat Third Generation (MTG) imaging and sounding satellites. The two instruments are called 'IRS' (being developed by OHB in Germany) and 'FCI' (being developed by Thales-Alenia Space in France TAS-F). The blackbody targets (BB) require very accurate thermal control, based on a liquid nitrogen jacket, a helium gas gap (where heat conduction through the gas is controlled by adjusting its pressure), and electric heaters. These, together with associated electronics, controls, tooling, flanges, harnesses, and cryogenic supply systems and their ancillary pipework, form the Optical Ground System Equipment (OGSE).

RAL Space require a supplier to provide mechanical support to finalise the design, analysis and support the manufacture of the blackbody targets, as well as to provide support for the assembly/integration leading to the delivery of these blackbody targets.. The supplier will be responsible for: • Detailed design activities as detailed in the Annex A - Tasks, focusing upon updates and modifications to existing CAD models of the system, and provision of final drawings for manufacture, and of layout/interfaces in each customer's facility. This will be in collaboration with STFC internal mechanical, thermal, EGSE, production and AIT teams. • Contribute to project design documentation, as well as lead assembly and test procedures associated with • Support in manufacture and procurement of the blackbodies and all associated mechanical ground support equipment (MGSE), in-line with the design activities above, in order to identify and liaise with various suppliers and manufacturers, as well as with STFC procurement procedures. • Active support and participation in the assembly and integration of the actual blackbodies themselves, in cooperation with STFC's AIT group, as an expert in the design and assembly.
