초록

The instant invention relates to turn-rate signal generating circuitry for interrupting slaving of the directional gyro and roll erection of the vertical gyro in a heading, attitude and reference system whenever the turn-rate of the vehicle on which the system is mounted exceeds a predetermined rate. Cutoff of slaving and roll erection eliminates acceleration induced dynamic errors produced by excessive turn rates and is effectuated in response to a turn-rate signal (i.e., an angular rate signal) generated indirectly from angular position (i.e., shaft po...
