A New Method for the Acquisition of Deviation Coefficients B and C at a Single Magnetic Heading
Jeong-Bin Yim, Yeong-Ho Sim
Abstract
This paper describes a new method for the acquisition of deviation coefficients, B and C, using a single observed deviation at a fixed compass heading. At first it discusses some problems in the synthesis of two coefficients, B and C, from various observed deviation values in the four USS warships. Then new theories and procedures for optimal coefficients, B and C, are dealt with and then the validity of the proposed method are evaluated. The result of findings indicates that the approximated coefficients, B and C, can give optimal approximation to an single observed deviation.
