The general trend in remote sensing is on one hand to increase the number of spectral bands and the geometric resolution of the
imaging sensors which leads to higher data rates and data volumes. On the other hand the user is often only interested in special information of the received sensor data and not in the whole data mass. Concerning these two tendencies a main part of the signal pre-processing can already be done for special users and dedicated tasks on-board a satellite.
The new on-board signal processing system should resolve the two following demands:
This is needed in several cases of tasks with a time restriction, for example fire monitoring, gale warning or damage of the environment. It is a technological experiment for the preparation of a future class of Earth-watch payload components.
