Abstract
A method for enabling indoor positioning of a mobile receiver, including: detecting an orientation of the mobile receiver; measuring light intensities using at least three effective visible light receiving areas positioned on the mobile receiver, wherein the at least three effective visible light receiving areas are orientated such that a measurement of light intensity of a light from the same light source by each of the at least three effective visible light receiving areas is different from the others; and producing an output which enables a 3-dimensional indoor positioning of the mobile receiver relative to a second coordinate system.
