- W2325101486 abstract "As space-rated technologies become more compact, more available, and less expensive over time, the concept of accomplishing traditionally large and expensive spacecraft missions using smaller nanosatellite-class spacecraft becomes increasingly feasible. This research focuses specifically on a CubeSat mission to assist with radio frequency (RF) domain verification; that of characterizing and mapping spot beams from communications satellites in geostationary orbit. By flying a CubeSat (or a constellation of CubeSats) through the edges of spot beams originating from geostationary communication satellites, the spot beam’s coverage area will be characterized. This research conducts a mission feasibility assessment, identifies the mission requirements to complete a spot beam mapping CubeSat mission, and examines various constellation configurations that could complete the spot beam mapping mission effectively. It was found that certain CubeSat constellations performed better than others, specifically regarding mapping time, responsiveness to changing conditions, spot beam detection capability, and overall mapping resolution. Constellations with CubeSat formations that utilized a specific spacing angle between themselves in an orbital plane could be tailored to produce spot beam maps with the best resolution; however constellations with a single plane of evenly-spaced CubeSats tended to produce better results over shorter durations. Separating CubeSats into separate planes tended to increase responsiveness and overall map resolution, but doing so required more time to form a comparable solution." @default.
