摘要:
A system and method of determining a position of an electronic device is presented herein. An image is displayed having at least one celestial object and a celestial object indicator for selecting a celestial object. The celestial object indicator is overlaid on the at least one celestial object. Data indicating a relative angle of the device with respect to the Earth in at least two dimensions is received at the processor. The time when the celestial object indicator is overlaid on the at least one celestial object is determined. The position of the electronic device is determined by comparing the location of the celestial object in the image data and relative angle information at the time of the indication to a database at least partially stored on the electronic device in response to an indication that the celestial object indicator is overlaid on the at least one celestial object.
