Phillips Laboratory and Systems Integration Engineering developed a two-theodolite, reflecting-surface technique for measuring the lines of sight (LOS) of sensors in rocket payload modules. A flat mirror, keyed to one theodolite provides a stable and adjustable reference by which the angular separation of sensor LOS's can be measured and referenced to the rocket's coordinate system. The rocket's Attitude Control System and external launch pad geodetic survey points are referenced to the vehicle's geometry using this procedure.
