1. A system for locating a near infra-red emitter, comprising:

  • a plurality of spaced receivers configured to receive one or more near infra-red signals, each of the receivers having an angular position coordinate value, stored in memory, associated with a designated angle of the receiver relative to a reference axis;

    each receiver configured to receive at least one locating near infra-red signal from the emitter, the locating signal including, at least in part, a plurality of pulses in at least one train of pulses;

    at least one locator processor, in communication with the spaced receivers, the at least one locator processor configured to;

    process the at least one near infra-red locating signal received at each receiver in a group of receivers in respective locating signal-receiving positions, to form a pulse count value in relation to a count of pulses above a pulse strength threshold;

    form a pulse count profile whose coordinates include the pulse count values and corresponding angular locations; and

    attribute a designated angular position coordinate value, corresponding to a maximum pulse count value in the pulse count profile, as a location value representative of at least the heading of the emitter.
