Tender Details

Tenders are invited for Truths Phase b2 - Optics Slit

TRUTHS (Traceable Radiometry Underpinning Terrestrial- and Helio- Studies) is an Element of the European Earth Watch Programme approved at 178th PB-EO (ESA/PB-EO(2019)31) for submission at CM19+ as a new Element, called “TRUTHS”. TRUTHS (Traceable Radiometry Underpinning Terrestrial- and Helio- Studies - is an operational climate mission, aiming to enhance by an order-of-magnitude our ability to estimate the Earth radiation budget through direct measurements and to establish a ‘metrology laboratory in space- to create a fiducial (International System of units - SI traceable) reference data set to cross-calibrate other sensors and improve the quality of their measurements. ·The TRUTHS Mission aims at measuring the incoming & outgoing energy from the climate system, including the spectral fingerprint needed to observationally attribute climate processes, with an accuracy needed to detect climate trends in the shortest possible time. The TRUTHS Mission has been authorised as part of the European Earth Watch Programme [ESA/PB-EO(2022)18 rev1] to start its Phase B2/Advance C implementation while authorisation to implement Phase C/D/E1 is subject to the availability of funding and authorisation at C-MiN 2025. Airbus Defence and Space has been selected by ESA as the Prime Contractor for Phase B2 with a mandatory option for Advance C. In this framework, Airbus Defence and Space Ltd will release an Invitation To Tender for the procurement of the Slit for the TRUTHS Phase B2. Supplier to confirm manufacturability of a high precision slit of 18micron width and 36 mm length to be machined into a foil material (0.5-1.0mm). The slit is to be used in a satellite optical instrument. Then to characterize the edge roughness and shape, flatness of the edges (to ensure all edges within a single plane), 2D shape accuracy achievable (straightness) and ability to control coating and finishing techniques for straylight reduction. The Invitation To Tender will be addressed to economic operators (including those deemed to act as Subcontractors) whose registered office is established in such Member and Associated States which, by the time of the Contract award decision, will be a participating State in the ESA TRUTHS Mission. To date, these are: Czech Republic, Greece, Romania, Spain, Switzerland, United Kingdom.
