The Traceable Radiometry Underpinning Terrestrial- and Helio-Studies mission (TRUTHS) is a planned European Space Agency (ESA) satellite. It is meant to "improve the accuracy, reliability and integrity" of Earth observation (EO) data,[2] and to be the first of a new class of "SI-traceable satellites" (SITSats) that will enable other EO missions to calibrate measurements with reference to them.[3]
