Abstract :
The SPOT5 remote sensing satellite was launched in May 2002. It provides continuity of the SPOT service owing to new characteristics of its two HRG (High Resolution Geometry) cameras and its two HRS (High Resolution Stereo) cameras. The image quality performances were assessed during SPOT5´s first two months of life (commissioning phase) and are still monitored during the commercial operations. To reach this goal, the CNES team uses a specific target programming in order to compute image correction parameters and estimate the performance of the system. This paper focuses on the radiometric performances of the different instruments, and on the corresponding tasks.
