This paper highlights the necessity of a rigorous approach both in the engineering calibration and geophysical calibration of the ERS-1 instruments which are two complementary activities. This need has been well understood and significant efforts in manpower and budgets have been, are and will be made to this aim. The engineering calibration is the full responsibility of the Agency, supported by the industrial contracts and all necessary elements are well identified, most of them already being under development. The preparation of the in-flight geophysical validation/calibration is of paramount importance. The quality analysis of the in situ/airborne measurements, their processing and assimilation/correlation with satellite data, as well as the data-base organisation and data retrieval, have to be organised and be ready before launch of the satellite. The same remarks apply to the development and deployment of the dedicated in situ/airborne measurement platforms.
