Abstract : PRECISION, AIRCRAFT SURVEILLANCE AND COLLISION AVOIDANCE SYSTEM. The real time data processing and display system developed makes use of a PDP11 minicomputer and a CRT display. These equipments have been programmed to accept input data from two aircraft; the input data takes the form of a set of four binary coded decimal numbers read from four time interval counters, plus standard range time (from a digital clock). Typically, a new field of numbers arrives several times a second. The PDP11 processes this input data in real time and generates a plan position display of the aircraft tracks and their projected positions. The display also presents tabular information such as aircraft heading, velocity and altitude, along with time and collision information. (Modified author abstract)
