Current commercial Earth Observation satellites have very restricted image processing capabilities on-board. They mostly operate according to a 'store-and forward' mechanism, where the images are stored on-board after being acquired from the sensors and are downlinked when contact with a ground station occurs. However, in order for disaster monitoring satellite missions to be effective, there is a need for automated and intelligent image processing onboard. In fact, the need for increasing the automation on-board is predicted as one of the main trends for future satellite missions. The main factors that hold back this concept are the limited power and computing resources on-board the spacecraft. This paper reviews existing image processing payloads of earth observing small satellites. An autonomous change detection system is proposed to demonstrate the feasibility of implementing an intelligent system on-board a small satellite. Performance results for the proposed intelligent imaging system are estimated, scaled and compared to existing hardware that are being used in the SSTL DMC satellite platform.
