ABSTRACT:
An apparatus and method for measuring the orientation of an observer vehicle with respect to a radiative target. The apparatus comprises a gnomon, a radiation sensor assembly and conventional electronic hardware for measuring the output of the radiation sensor assembly. The radiation sensor assembly is divided into four quadrants each having an equal number of sensor element which emit a current in the presence of radiation. The individual currents from each respective sector are summed by said conventional electronic hardware to provide the orientation/angular relationship between the radiative target and the apparatus.
