Network control systems for large-scale constellations of small satellites are of critical importance to the successful and safe operation of smallsat systems – especially in the case of remote sensing networks but also for other applications. As the level of complexity of the space segment and the ground segment of these networks increases so does the level of complexity of the network control systems that are used. Today small satellite constellations such as those represented by Planet and Spire represent the two largest small satellite constellations in operation, but in the near future, there are many new constellations that may require network control of many thousands of smallsats. There are challenges associated with initially deployment, configuration of spare satellites, operation of large constellation, and de-commissioning and de-orbit of smallsats that require a high level of sophistication and technical expertise. All of these levels of complexities and methods to create effective network control systems for large-scale constellations are addressed in this chapter.
