1. A mobile device configured to be used in a wireless communication network, the mobile device comprising: an image capture device; at least one sensor configured to measure a first orientation of the mobile device; and a processor communicatively coupled to the image capture device and the at least one sensor and configured to: identify an object in an image captured by the image capture device; estimate a first location of the object identified in the image relative to the mobile device based on the captured image and the first orientation; determine an estimated position of the mobile device based on signals received from one or more wireless communication networks; use the estimated position of the mobile device to access almanac data to determine a second location of the object relative to the mobile device; and use the second location of the object relative to the mobile device and the first location of the object relative to the mobile device to determine a calibration correction for the at least one sensor.
