Abstract :
An internal study has been carried out at ESTEC/WSP (Onboard Image and Signal Processing Section) about compression of synthetic optical multispectral images which will reflect characteristics of future satellites´ imagers. The images produced by these instruments are composed by up to 15 bands in the range of 400-1050 nm, with radiometric resolutions of 8-16 bpp and a spatial resolution of around 250-300 m. The aim of this study is to evaluate the effectiveness of a fast and simple onboard data compression process to reduce the amount of data to be transmitted to ground stations or to be stored on the satellites´ on-board recorders
