Deviation Calculator
Calculate magnetic compass deviation coefficients from eight compass swing readings and turn them into a curve, table, and quick model check.
Calculator
Enter the compass swing readings
Add observed deviation for the eight main headings. The calculator returns A/B/C/D/E coefficients, a deviation curve, and a compact record for checking the model.
A / B / C / D / E coefficients
Calculated from the eight entered deviation readings.
Range: —
Deviation record
Deviation is the entered value, model is the curve value, and residual is the difference between them.
