A position finding and collision avoidance system derives, at an Own station within the service area of an identified SSr at a known location, differential azimuth (A), differential time of arrival (T), identity and altitude data regarding any transponder-equipped Other station or stations within a predeterminable region surrounding Own station, from standard ATCRBS interrogations and replies. These data are used to compute the positions of Other stations for display at Own station.
