A radio location system for airport surface traffic, based on the mode S squitter is presented. The address-selective mode S allows positioning with identification as well as bidirectional data transmission between ground station and aircraft. The expected accuracy is between 10 and 20 m. Transponder and data link are standardized for the mode S. The location can be performed with a small number of sensors using time of flight difference measurements. The basis of the location system is the squitter sent every second by the transponder. Tests with an experimental sensor in a strongly perturbed environment show that time of flight difference measurements and angle measurements can be performed using the amplitude monopulse technique. The requirements for the signal processing are very high.
