A method for precision collaborative targeting includes determining information indicative of a current location and of a known remote location. A first distance is determined from the current location to the known remote location. A sensor is slewed towards an unknown remote location, the sensor being initially directed from the current location to the known remote location. The distance from the current location to the unknown remote location is measured. Information indicative of the location of the unknown remote location is determined from the amount of slewing and the distance from the current location to the unknown remote location.
