The Open Prototype for Educational NanoSats (OPEN) is a system that focuses on reducing spacecraft mission costs. It provides a set of designs that is freely available to anyone online. The OpenOrbiter CubeSat provides designs to create a small satellite using economical materials available allowing a parts budget of under $5,000. One aspect of this design is CubeSat payload processing software. This is the process of taking a single image, or multiple images taken at the same time, and manipulate them. This manipulation an include compression, mosaicing, super resolution, or any combination thereof. The first step in this process is …

A small satellite in a low-Earth orbit (e.g., approximately a 300 to 400 km altitude) has an orbital velocity in the range of 8.5 km/s and completes an orbit approximately every 90 minutes. For a satellite with minimal attitude control, this presents a significant challenge in obtaining multiple images of a target region. Presuming an inclination in the range of 50 to 65 degrees, a limited number of opportunities to image a given target or communicate with a given ground station are available, over the course of a 24-hour period. For imaging needs (where solar illumination is required), the number …
