OptionalpositionHow much position history to retain per aircraft. Unbounded (subject to memory) if omitted.
OptionalstaleMilliseconds an aircraft can go without an update before aircraft:lost fires. Defaults to 60000.
OptionalsweepMilliseconds between staleness sweeps. An aircraft is dropped on the first sweep after staleAfterMs elapses, so this bounds how late aircraft:lost can fire. Defaults to 1000.
