Beschreibung
Zusammenfassung:	A multilateration system controller comprises time of arrival correlator for performing a time of arrival correlation using a time of arrival window based on receiver location applying the window to received synchronised time of arrival data to determine which data has a low and which data has a high probability of originating from a single aircraft and passing at least the data with a high probability to a multilateration processor which performs a multilateration to determine the position of the aircraft. The time arrival window comprises the time difference that is experienced for receipt of a signal by receivers in a multilateration system.
