Method and device for simultaneously identifying and correcting measurement errors of a magnetometer

摘要

The device (1) includes a calculation module (5) connected to a magnetometer (2) via a bus (4). A multiple connection (6) transmits all the information required about the aircraft on which the magnetometer is mounted. The calculation module uses a bespoke algorithm to calculate a matrix (E) whose coefficients represent the characteristic parameters of all the perturbations affecting the magnetometer. A second calculation module (7) collects data through other two links (8,9) and calculates the coefficients of a translation matrix (M). A central module (10) is connected to the magnetometer and the calculation modules and determines the correction model to be applied to calculate the effective magnetic field. The results are transmitted via a link (13) to an analysis device.
