Abstract
A method for navigating a movable pool related platform (PRP), the method includes moving the movable PRP along a home direction, wherein the movable PRP is associated with a gyroscope and with a magnetometer, wherein the moving is based on a gyroscope-based direction of movement estimate, wherein the gyroscope was aligned with the magnetometer. The magnetometer was calibrated during a calibration process that includes (i) determining, by a controller of the movable PRP, a mapping between magnetometer readings and a magnetometer-based direction of movement estimate; wherein the mapping is based, at least in part, on a first range of the first axis magnetometer readings and a second range of the second axis magnetometer readings; and (ii) performing an alignment iteration that comprises aligning, by the controller, between the magnetometer-based direction of movement estimate and the gyroscope-based direction of movement estimate.
