Byron:While working on a possible ,Nav curriculum, of a day at sea, and the many possible navigation Navigation day's work in Navigation.
The work brings back the many routines and needs of a day’s work at sea at navigation. I had many ideas of the real problems the navigator faces. The one that I felt the strongest. About and one of the most important is the ships compass Gyro.
The normal procedure is using the Azimuth Circle to find set the error,this is a real problem. in that it is not accurate.
Yes, to monitor compass error is good and proper at sea, but to set the compass (gyro) using the Azimuth Circle is wrong.It is delicute and offten off but needed in deep water.
While inport or inharbor,There are many other ways to get that accurate, down to a decimal of a degree.
The Franklin piloting Technique using bearings of Navaids using a bearing circle is more accurate than a bearing of the sun (Azimuth) the same equipment that is used to pilot the ship into hazardous water is more accurate, more than one object is used so that a accurate direction is down to the decimal. The navigation people at Navlist could evaluate and comment. I azimuth Circle and the taking of bearings, and the Franklin Technique. A lot could be learned and a real help to the shipping industry as well as the sea servaces.
Do you have the equipment and the know how to evaluate? Let us help our navy and Coast Guard.
