Abstract: A Non-Geostationary Satellite Orbit (NGSO) satellite system is described that implements one or more user route tables and a plurality of pre-calculated backbone route tables at its satellites. The user route tables track user connectivity to the satellites, and each of the backbone route tables defines a snapshot of a time-varying backbone topology seen by a particular satellite. During operation, a satellite selects different backbone route tables as the topology changes over time, and receives updates to the user route tables when connectivity changes occur between the users and the satellites. The decoupling of the user route tables from the backbone route tables at the satellite reduces the computational burden on the NGSO system, as the backbone route tables are calculated in advance and the NGSO system is subsequently tasked with a computationally lower burden of performing real-time updates to the user route tables.
