Hybrid positioning methods and electronic apparatuses are provided. A representative method includes: obtaining initial location information; computing initial moving information based upon the sensor readings; computing estimated location information based on the initial moving information and the initial location information; acquiring geographical location readings if a location update condition is satisfied; generating reference location information based on the geographical location readings acquired; comparing the estimated location information with the reference location information to obtain a deviation information; computing a calibrated moving information based on the estimated location information and the deviation information; and computing a calibrated location information based on the deviation information, calibrated moving information and the estimated location information.

Hybrid positioning method, electronic apparatus and computer-readable recording medium thereof

Electronic devices and methods for providing location information are provided, of which a representative method includes: generating sensor readings corresponding to sensed motion of the electronic device; determining a reference location information; computing a GPS-fused location information based on the reference location information and the sensor readings; generating a GPS-required event based on a change of the GPS-fused location information; generating a GPS-not-required event responsive to the reference location information being determined; receiving the GPS-fused location information and one of either the GPS-required event or the GPS-not-required event; responsive to the GPS-required event being received, operating the GPS receiver in a location information-acquiring mode during which the GPS receiver generates geographical location readings; and responsive to the GPS-not-required event being received, operating the GPS receiver in a power-saving mode during which the GPS receiver is deactivated.
