A promising direction in the evolution of air traffic control systems is the deployment of multilateration surveillance systems (MLAT) for aircraft positioning. Automatic dependent surveillance broadcast (ADS-B) systems are proposed as a communication technology for MLAT systems. The implication is that information will be broadcast automatically throughout the flight. Fundamentally, the aircraft positioning problem can be solved by determining the time difference of the arrival of signals transmitted by the on-board transponder and decoded at receiving stations. Positioning can be made more effective and accurate by implementing state-of-the-art data processing methods. In this paper we present our algorithm for optimum estimation of aircraft coordinates based on the least squares method and report on theoretical and experimental studies of a MLAT observation system and factors affecting its operation. Using a known layout of ground stations, we investigate precision performance within the operating range of the system.
