渔船磁罗经平行固定校正法,是针对小型渔船磁罗经的校正而言,其校正场地适合渔港码头。具体操作程序是: 一、校正前的准备工作 1.校正场地的选择。利用渔船经常停靠的人工或天然渔港的码头作为校正场地,即能方便渔民和工作人员,又能充分地利用了原有条件。无论是直线形、三角形、半圆形等的码头,只要能够使渔船做180°调头,均可做校正场地。同时,要注意以下两个问题: ①确定做消除半圆自差用的主方位。直线形的码
For the calibration of the magnetic compass for small fishing vessels, the correctional method for the magnetic compass of fishing vessels is suitable for the fishing port. The specific operating procedures are: First, the preparatory work before the correction 1. Calibration site selection. The use of docks at artificial or natural fishing ports where fishing boats often dock as a calibration site can facilitate the fishermen and staff and make full use of the existing conditions. Whether it is straight, triangular, semicircular and other docks, as long as the fishing boat can make 180 ° turn around, can do to correct the site. At the same time, pay attention to the following two questions: ① determine to do to eliminate semicircle difference with the main azimuth. Linear code
