| description | PURPOSE:To continuousely and accurately measure an azimuth by mounting two or more antennae arranged to a navigation body for receiving a satellite radio wave, a position and azimuth operating apparatus, an angular velocity sensor having a yaw axis as an input axis and related devices. CONSTITUTION:The radio wave from a GPS satellite received by two antennae 1, 2 arranged to a ship body on the bow and stern line thereof at a predeter mined interval is 1 inputted to a GPS position operation part 4 and a GPS azimuth operation part 3 to calculate the position and azimuth of the ship body. The azimuth output from the operation part 3 is subjected to comparative operation along with the azimuth obtained by integrating the output of a vibra tion gyroscope 10 by a comparator C and the residual differential angle thereof is inputted to a compensating operation part 13 and multiplied by K to be fed back to the adding part E on the input side of an integrator 12 as an oppo site code. The output angular velocity of the gyroscope 10 is integrated and the azimuth follows the azimuth from the operation part 3. Therefore, even when the output cycle of the operation 3 becomes long, the azimuth angle is interpolated by the azimuth due to the gyroscope during this period. |
