This study was conducted to calculate all the Poisson's deviation coefficients, and to obtain the effect of changing magnetic latitude by computer simulation. These coefficients consist of the induced magnetism coefficients and the permanent magnetism one. In our electronic compass, these coefficients were calculated by measuring the vessel's magnetic force in the rectangular coordinates on four magnetic headings (N, E, S, W) under the vessel in level condition, and on another heading in any pitching or rolling condition. After that, the electronic compass can always indicate the true magnetic heading at any magnetic latitude and any vessel's attitude that was confirmed by the computer simulation. A model vessel was used in the simulation in which the vessel was navigated from Tokyo to Fremantle by way of Singapore. The result was given a good performance compared with the ordinary magnetic compass.
