Abstract
To cater for the positioning of an aircraft in a boundary zone between two adjacent multilateration systems, the controller () in one system receives Time Difference of Arrival data provided by the controller () in the second system. The controller () derives the TDoA data from time of arrival data provided by its receiver stations (-). By furnishing TDoA data the timings of the two systems do not need to be synchronised. The controller () uses the TDoA data and also time of arrival data from its local receiver stations (-) to perform a multilateration to determine the location of the aircraft ().
