On-Board image compression for space missions

摘要

On-board space instruments produce more and more high amount of data due to the increase in both resolu- tion and number of bits per pixel, not compensated by the reduced swath. Due to the stringent limitations (in terms of mass and power) which apply to on-board equipment, it is essential to reduce to a minimum the on-board sto- rage capacity and the on-board transmission rate needed to fullfill the mission: on-board image compression is a very powerful tool to optimise the resources. The availability, for spaceborne applications, of highly Integrated circuits allows to implement on board very Sophisticated real-time compression schemes and then to Improve the performances of on-board compression.
