Abstract: A magnetic field measuring apparatus includes a first processor, a second processor, a motion sensor and a magnetic field sensor. The second processor has higher processing capability than the first processor. The first processor makes the second processor perform certain processing. When it is determined that the state of motion measured by the motion sensor is at a predetermined level or more, the second processor performs a magnetic field correction setting operation as one of the certain processing. The magnetic field correction setting operation involves retrieving measurement values of magnetic field from the magnetic field sensor which are measured at different postures according to a change of the state of motion, and determining an offset correction value for the geomagnetic field based on the measurement values.

Abstract: An electronic device includes a GPS unit, a GPS information acquisition unit, a sensor information acquisition unit, and a reception condition determination unit. The GPS unit receives a radio wave from at least one of a plurality of positioning satellites. The GPS information acquisition unit acquires ephemeris information by the GPS unit and acquires satellite arrangement information of each of the plurality of positioning satellites acquiring the ephemeris information. The sensor information acquisition unit acquires geographical condition information of a current location at which the electronic device is present. The reception condition determination unit identifies the number of positioning satellites that the receiving unit can capture at the current location among the plurality of positioning satellites acquiring the ephemeris information based on the geographical condition information of the current location and the satellite arrangement information.
