Abstract
Operations in cislunar space are expected to greatly increase over the next decade, which will place a heightened demand on position, navigation, and timing (PNT) architectures. Existing PNT systems will be unable to support this growth, evidencing the need for a new cislunar PNT infrastructure. This study defines and parameterizes the design space for cislunar PNT architecture development, with the goal of enabling design space exploration and architecture trade studies. Design choices such as orbit type, architecture symmetry, and preferred design variables and their ranges are discussed. An environment for modeling and evaluating PNT architectures is developed and demonstrated on a subset of the defined design space. Preliminary results are shown to exhibit the type of data and trends to be expected from these studies. A discussion of optimization algorithms that can leverage this environment to fully explore the defined design space and identify optimal designs is presented.
