Abstract: Airfield surveillance unit (11) for detecting airfield traffic and airfield multilateration system comprising such airfield surveillance unit. The airfield surveillance unit comprises a power supply module (113), a first radio antenna (111) configured to receive an aircraft transponder signal, a receiver module (112) coupled to the power supply module (113) and to the first radio antenna (111) and comprising a first data communication port (1122, 1123). The receiver module (112) is operable to convert the aircraft transponder signal received by the first radio antenna (111) to a multilateration-purpose signal for transmission via the first data communication port. The airfield surveillance unit further comprises a second radio antenna (118) and a 5G communication module (117) coupled to the power supply module (113) and configured to be coupled to the second radio antenna for operating as a transceiver for a mission critical private 5G cellular network.
