LPC based multispectral compression techniques applied to optical imaging spectrometer instruments

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.
