Onboard Coaddition of Multiple Image Frames to Increase Signal to Noise Ratio and Facilitate Target Tracking(NPO-50487-1)

This software is part of the agile science framework and the Near Earth Asteroid Scout (NEAScout) CubeSat flight software. The purpose of this software is to automatically increase the signal to noise ratio of image data, acquired by a spacecraft, without the need for data downlink. This is accomplished by taking multiple images, in rapid succession, and merging the data between these frames together, while accounting for instrument jitter and other intermediate effects. Increasing the signal to noise ratio also eliminates single image artifacts, like cosmic rays, which results in a higher fidelity product for subsequent processing. This process creates a single data product, representing the data from multiple image frames. This product can then be downlinked with a fraction of the bandwidth of the original, or further processed onboard the spacecraft.
