Abstract
In a distributed management scheme for LEO satellite networks interactions between a satellite and the designated fixed center occur according to a time schedule and only when the designated center is in the coverage area of the payload. For exception/alarm reporting and real-time configuration updates the interaction varies with time. Interactions of this type occur between a satellite and the management center that is “nearest” to the payload or satellite at the time instant at which the network event occurs or configuration upload is needed. The nearest management center for a payload is the center that can be reached from the payload with fewest number of crosslink hops. A central network operation center determines, prior to payload launch, the association between satellites and management centers for routine information exchange, and the nearest management center for the payload for different snapshots of time.
