Software defined radios (SDRs) are poised to significantly enhance the future of small spacecraft communications. They allow signal processing to be performed on a computer by software rather than requiring dedicated hardware. The SDR takes data from the flight computer and converts it into an analog signal that is transmitted via the spacecraft antenna. Because the signal processing is done in software, the radio can be easily reconfigured.
Data is prepared for transmission by TCP stack software onboard the OpenOrbiter Spacecraft and placed in a queue while the spacecraft is listening for a signal from a ground station. When a …

Previous work discussed critical differences in planning, developing hardware for and executing a high altitude balloon (HAB) mission. One area where this difference is less pronounced is in software development, allowing HABs to be utilized as a ‘software testbed’ for many orbital missions. This paper provides an overview of the software development process for both orbital and HAB craft, highlighting differences between the two processes and the numerous similarities. It concludes by presenting a framework for analyzing the suitability of HAB testing for small satellite software.
