Electronic device for determining position and method for operating the same

An electronic device, comprising:

• a magnetic sensor;
• a communication interface;
• and
• a processor configured to:
• identify an altitude of the electronic device,
• send information on the altitude of the electronic device through the communication interface,
• receive a first geo-magnetic map corresponding to the altitude including geo-magnetic data for each of a plurality of positions in an area corresponding to the altitude of the electronic device through the communication interface,
• compare the received first geo-magnetic map with geo-magnetic data sensed by the magnetic sensor, and
• provide a position of the electronic device using a result of the comparison.

A method for operating an electronic device, the method comprising:

• identifying an altitude of the electronic device;
• selecting one of a first geo-magnetic map and a second geo-magnetic map corresponding to the altitude of the electronic device, the first geo-magnetic map including geo-magnetic data for each of a plurality of positions at a first altitude in an area, and the second geo-magnetic map including geo-magnetic data for each of the plurality of positions at a second altitude in the area;
• comparing the selected geo-magnetic map with sensed geo-magnetic data;
• and
• providing a position of the electronic device using a result of the comparison.
