Abstract
A method for position measurement of a portable electronic device is provided. The method includes receiving, from a first satellite, first satellite information and state information of the first satellite information, receiving other state information of the first satellite information from a server that receives the other state information of the first satellite information from a terrestrial observatory, and using the first satellite information for the position measurement of the portable electronic device when the state information of the first satellite information received from the first satellite is unhealthy and the other state information of the first satellite information received from the server is healthy, wherein healthy state information indicates that satellite information may be used for the position measurement of the portable electronic device and unhealthy state information indicates that the satellite information may not be used for the position measurement of the portable electronic device.

9. An apparatus comprising:
-
a first communication module; a second communication module; and a processor configured to; receive, using the first communication module, location information corresponding to the apparatus and first state information corresponding to a satellite from the satellite; receive, using the second communication module, second state information corresponding to the satellite from an external device; determine a state of the satellite based at least in part on the first state information or the second state information; identify a position of the apparatus using the location information based at least in part on a determination that the state satisfies a specified condition; and refrain from identifying the position using the location information based at least in part on a determination that the state does not satisfy the specified condition. - View Dependent Claims (10, 11, 12, 13, 14, 15, 16, 17, 18, 19)

20. A method comprising:
-
receiving, at an electronic device including a first communication module and a second communication module, location information corresponding to the electronic device and first state information corresponding to a satellite from the satellite using the first communication module; receiving, using the second communication module, a second state information corresponding to the satellite from an external device; determining a state of the satellite based at least in part on the first state information or the second state information; identifying a position of the electronic device using the location information based at least in part on a determination that the state satisfies a specified condition; and refraining from identifying the position using the location information based at least in part on a determination the state does not satisfy the specified condition. - View Dependent Claims (21, 22, 23, 24, 25, 26, 27)

28. A non-transitory machine-readable storage device storing instructions that, when executed by one or more processors, cause the one or more processors to perform operations comprising:
-
receiving, at an electronic device including a first communication module and a second communication module, location information corresponding to the electronic device and first state information corresponding to a satellite from the satellite using the first communication module; receiving, using the second communication module, a second state information corresponding to the satellite from an external device; determining a state of the satellite based at least in part on the first state information or the second state information; identifying a position of the electronic device using the location information based at least in part on a determination that the state satisfies a specified condition; and refraining from identifying the position using the location information based at least in part on a determination the state does not satisfy the specified condition.

29. A method for position measurement of a portable electronic device, the method comprising:
-
receiving, from a satellite, satellite information including state information of the satellite; receiving other state information of the satellite from an external device; and determining whether to use the satellite for the position measurement of the portable electronic device by comparing the state information of the satellite received from the satellite and the other state information of the satellite received from the external device, wherein healthy state information indicates that the satellite information may be used for the position measurement of the portable electronic device and unhealthy state information indicates that the satellite information may not be used for the position measurement of the portable electronic device.

30. A portable electronic device, the device comprising:
-
at least one processor; a memory; and at least one program stored in the memory and configured to be executed by the at least one processor, wherein the program comprises instructions for; receiving, from a satellite, satellite information including state information of the satellite; receiving other state information of the satellite from an external device; and determining whether to use the satellite for position measurement of the portable electronic device by comparing the state information of the satellite received from the satellite and the other state information of the satellite received from the external device, wherein healthy state information indicates that the satellite information may be used for the position measurement of the portable electronic device and unhealthy state information indicates that the satellite information may not be used for the position measurement of the portable electronic device.
