Abstract: This paper studied the observation error of declination with bias current by FHD-1 proton precession magnetometer in theory. The result indicates that the error is increased with the value of declination and bias current drift, which has significance to improve the precision of declination observation by that magnetometer at stations.
Key words: Proton precession magnetometer, Declination, Observation error, Bias current
