Abstract

A method of tracking the Sun's apparent position in the sky utilizes location and time data provided by GPS, magnetic field data provided by a three- axis magnetometer and compared to a value computed (10) for said location and time, based on stored global model data (20), and data from an optical alignment sensor (40). Apparatus orientation is determined by comparing the calculated and the measured magnetic field vectors, while the current apparent position of the Sun is calculated in horizontal coordinates and both results are used to move the payload (60) to a position within the range of the optical alignment sensor (40), which is then used for fine tuning and precise positioning (70, 80). Self-organizing map structure provides for non-linearity and system self-calibration, to achieve high accuracy when dead reckoning.
