Abstract
A GNSS enabled mobile device moves from a first area where GNSS signal quality and/or level is above a threshold to a second area where GNSS signal quality and/or level is below the threshold. The GNSS enabled mobile device in the second area determines its own location utilizing previous GNSS measurements in the first area. GNSS signals are received to calculate GNSS measurements whenever the GNSS enabled mobile device is in the first area. The calculated GNSS measurements are utilized to determine a location of the GNSS enabled mobile device within the first area. The GNSS enabled mobile device in the second area utilizes the most current GNSS measurements in the first area to determine its own location. Sensors such as an image sensor, a light sensor, an audio sensor and/or a location sensor are used to refine the location of the GNSS enabled mobile device in the second area.
