Abstract
A method for compensating a movement of an antenna structure having a directive antenna mounted thereto is disclosed. The method comprises obtaining sensor data from a motion sensor, where the sensor data is indicative of the movement of the antenna structure relative to a reference orientation. Moreover, the motion sensor is associated with a set of calibration parameters such that when applied to the obtained sensor data, calibrated sensor data is formed. Further, the method comprises generating a compensation signal at an output for controlling a beam direction of the directive antenna based on the formed calibrated sensor data such that the beam direction is an intended direction of the directive antenna and such that the (unwanted) movement of the antenna structure is compensated. The method further comprises re-calibrating the motion sensor in order to generate a set of calibration coefficients upon either one of an expiry of a predefined time period, a counter reaching a counter threshold, or upon a measured antenna parameter or signal parameter diverging from a parameter range. Once, one of these conditions are fulfilled, the re-calibration is performed by obtaining a recei…
