PURPOSE:To enable a digital display of the ship's head bearing, speed errors, speed and latitude by providing an automatic speed errors corrector to enable the execution of the speed errors adaptable to various types of ships. CONSTITUTION:A bearing signal is fed to an automatic speed errors corrector 30 from a bearing synchronizer 22 of a master compass 1. The corrector 30 converts the signal into a digital bearing data with an S/D port 34 and receives data of the speed and latidude of own ship from a log 38 and an NNSS39 as sensors to compute the speed errors on an S program whereby an analog signal of the speed errors is automatically set on a modulator 35 on line. One or both of automatically/manually switching speed and latitude buttons of an operation panel 36 are changed over to the manual mode and numerals are digitally displayed for the ship's head bearing, speed errors, speed and latitude at the position specified with the shift from the manual mode to automatic mode. |
