Summary: | The invention is a method for determining the orientation of a multi-component receiver where the preferred embodiment of the method makes use of an approximation of the relative bearing angle provided by a relative bearing sensor. The method comprises the steps of scanning various angles around the approximated relative bearing angle provided by the relative bearing sensor and for each scanned angle rotating the data into the true earth frame using a given scanned angle and measuring the polarization angle of the rotated data in the horizontal plane and calculating a weighted sum of the differences between the source azimuth and the estimated azimuth from the polarization. |
