Abstract
In a communication system (10) having at least one control center (24) and multiple satellites (12), the satellites (12) operate according to tables (80), wherein each satellites table becomes obsolete at a known time referred to as the exhaustion time. The earliest exhaustion time of all satellites (12) is determined and sent to the satellites (12) in the form of a message or a time-tagged update table (150). When the earliest exhaustion time is reached without updating the satellite (12), the satellites (12) enter default operation at that earliest exhaustion time. The satellites (12) continue default operations until otherwise instructed by the control center (24).
