Abstract
Abstract Each towed field artillery piece in a battery of field artillery pieces uses a heading reference system 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 includes a "master" azimuth gyro 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.

Claims Analysis
Total Claims: 13
Claim 1
Independent Claim
185 words
A method for aiming a plurality of towed field artillery pieces in a battery of said pieces, comprising: mounting each of a plurality of heading reference systems on a corresponding one of the plurality of field artillery pieces; activating a mobile gyrocompass and location system for providing alignment and location data for each of the field artillery pieces; initializing each of the heading reference systems to an arbitrary heading; transporting the activated mobile gyrocompass and location system to each of the field artillery pieces, in turn; transferring the alignment and location data for each piece from the mobile gyrocompass and location system to the heading reference system mounted to said each piece, in turn, until all of the pieces are in azimuth alignment and are located, and displaying said azimuth alignment and location; transporting the activated mobile gyrocompass and location system to a fire direction center; and transmitting heading and location data from the fire direction center to each azimuth aligned and located piece, and displaying said transmitted data for enabling a gunner to correct the aim of said each piece during a firing mission.
Claim 2
Independent Claim
185 words
A method for aiming a plurality of towed field artillery pieces in a battery of said pieces, comprising: mounting each of a plurality of heading reference systems on a corresponding one of the plurality of field artillery pieces; activating a mobile gyrocompass and location system for providing alignment and location data for each of the field artillery pieces; initializing each of the heading reference systems to an arbitrary heading; transporting the activated mobile gyrocompass and location system to each of the field artillery pieces, in turn; transferring the alignment and location data for each piece from the mobile gyrocompass and location system to the heading reference system mounted to said each piece, in turn, until all of the pieces are in azimuth alignment and are located, and displaying said azimuth alignment and location; transporting the activated mobile gyrocompass and location system to a fire direction center; and transmitting heading and location data from the fire direction center to each azimuth aligned and located piece, and displaying said transmitted data for enabling a gunner to correct the aim of said each piece during a firing mission.
Claim 3
Dependent Claim
125 words
A method as described by claim 1, wherein transferring the alignment and location data for each piece from the mobile gyrocompass and location system to the heading reference system mounted to each piece includes: mounting an alignment plate to a "slave" gyro in the heading reference system mounted to each piece; disposing a "master" gyro included in the mobile gyrocompass and location system on the alignment plate, for each piece, in turn; connecting each "slave" gyro to the "master" gyro; entering alignment data from the mobile gyrocompass and location system into each heading reference system, in turn; the mobile gyrocompass and location system storing grid location data from the respective field artillery piece; and displaying the alignment and location data for each field artillery piece.
Claim 4
Dependent Claim
52 words
A method as described by claim 1, wherein transmitting heading and location data from the fire direction center to each azmuth aligned and located piece and displaying said transmitted data includes: connecting the fire direction center to each piece through a ground cable from the fire direction center to said each piece.
Claim 5
Dependent Claim
38 words
A method as described by claim 2, including: sensing data corresponding to the attitude of the turret of each field artillery piece; and displaying said sensed data with the alignment and location data for each field artillery piece.
Claim 6
Dependent Claim
29 words
A method as described by claim 4, wherein: sensing data corresponding to the attitude of the turret of each field artillery piece includes sensing elevation, roll and pitch data.
Claim 7
Dependent Claim
58 words
A method as described by claim 1, wherein: transporting the activated mobile gyrocompass and location system to each of the field artillery pieces, in turn and transporting the activated mobile gyrocompass and location system to a fire direction center includes: disposing the mobile gyrocompass and location system on a vehicle and driving said vehicle to effect said transporting.
Claim 8
Dependent Claim
56 words
A method as described by claim 2, wherein activating a mobile gyrocompass and location system for providing alignment and location data for each of the field artillery pieces includes: activating the "master" gyro for providing a north reference; and activating a global positioning system for providing the grid location of each of the field artillery pieces.
