The work presented here addresses practical aspects of data fusion to implement a prototype of advanced surface movement guidance and control systems (A-SMGCS). It reflects recent experiences in an on-going project to fuse data from available and future sensors at Madrid-Barajas airport: automatic surface detection equipment (ASDE), millimeter wave sensor (MWS), airport surveillance radar (ASR) and mode-S multilateration. Simulation results show system accuracy and robustness in representative situations, taking into account the airport configuration.
