<p>Each towed field artillery piece (4, 6, 8, 10) in a battery (2) of field artillery pieces uses a heading reference system (12, 14, 16, 18) having a 'slave' azimuth gyro, pitch and roll angle sensors and a readout display for correcting azimuth and elevation during a fire mission. A master system (30) includes a 'master' azimuth gyro (33) which is mechanically lined up with the axis of the 'slave' azimuth gyros in the heading reference systems. The master system transfers azimuth information to the slave system, whereupon the slave system acts as a repeater for the information given by the master to confirm congruency of the master and slave systems and provides the present location of the respective field artillery pieces.</p> |
