When You Have More Satellites than People: The Evolution of CYGNSS Flight Operations

The flight operations of the Cyclone Global Navigation Satellite System (CYGNSS), a constellation of eight microsatellites built and operated by Southwest Research Institute (SwRI), designed to improve the intensity forecasts of Tropical Cyclones, has seen a litany of changes to its concept of operations, software, processes, and personnel. In this paper, we detail how the operations team responded to several challenges such as the reduction in personnel after the Launch and Early Orbit Operations phase, the addition of a downlink antenna in Japan, high-fidelity collection requests during the unusually active 2017 Atlantic hurricane season, and the increased demands of team members from other projects. These pressures forced the CYGNSS operations team to innovate their way to efficient operations. These innovations were enabled by embracing modern open-source tools such as Django, Bokeh, Git, the various libraries available in the Python programming language, and the capabilities that come with all of our operations engineers being competent in software development. The CYGNSS team took the approach of automating the most time-intensive tasks first, which freed up time to carefully design and test more elaborate automation solutions. We utilized the spirit of the Agile Methodology to make incremental improvements to our software suite which further enabled more sophisticated automation. Finally, we chart a path forward to fully closing the automation loop between our mission planning, and real-time Command and Control.
