METHOD TO PREDICT LOCAL GEOMAGNETIC DISTURBANCE FIELD AND ITS PRACTICAL APPLICATION |
摘要 |
A method for correcting geomagnetic reference field includes measuring Earth magnetic field elements at least one known geodetic position. Earth magnetic field elements are measured at a position proximate the location. A disturbance function is determined from the Earth magnetic field measurements made at the at least one known geodetic position. A magnetic disturbance field measurement transfer function is estimated between the at the at least one known geodetic and proximate positions to estimate a disturbance function at the proximate position. The estimated magnetic disturbance function is used to correct geomagnetic reference field or measurements made at the location. |
