| Zusammenfassung |
| SIMBIO-SYS consists of integrated sensors, including a stereo imaging system (STC), a high-resolution imager (HRIC) and a visible–near-infrared imaging spectrometer (VIHI). In order to properly extract and derive the relevant scientific information, an in-depth characterization of the instrument effects is required from subsystems to integrated systems levels. The main goal of the on-ground calibration is to evaluate the instrumental responses as a function of various parameters that can evolve while the instrument will be in operation. The on-ground calibration of the SIMBIO-SYS instrument will consist in two steps. The first one will be done at the channel level by Selex-Galileo (Firenze) and the scientific team of each channel. Once integrated, the performances of SIMBIO-SYS will be then evaluated at Institut d’Astrophysique Spatiale (Orsay). The major objectives of the calibration at the instrument level are: 1- cross- and absolute radiometric, namely to connect the instrumental signals recorded with actual values of calibrated sources radiance; 2- straylight evaluation; 3- calibration with mineral analogues. As a secondary goal, the on-ground calibration at the instrument level is a unique opportunity to validate operational procedures and test the reception and quick look analyze of the instrument telemetry. In this poster, we will present in detail the on-ground calibration setup developed at IAS for this space instrument. |
