The HelioSwarm Observatory is a nine-spacecraft swarm design, consisting of one Hub and eight Node spacecraft co-orbiting the Earth in a ~13.7-day orbit. Each Node separates from the Hub during the Node Commissioning Phase, and the Nodes’ sole source of tracking is inter-satellite relative ranging with the Hub. This study characterizes how soon the relative ranging should occur post-separation to maintain a reasonable knowledge of the Nodes’ position relative to the hub and quantifies how often, and at what measurement cadence, relative ranging needs to occur during the early days of commissioning.
