Abstract

A method of selecting a satellite positioning system which is used in positioning by a positioning device capable of performing positioning based on a plurality of satellite positioning systems includes acquiring given support information which is referred to in selecting a satellite positioning system, and selecting a satellite positioning system which is used in positioning from the plurality of satellite positioning systems, on the basis of the support information.

Claims

1. A method of selecting a satellite positioning system which is used in positioning by a positioning device capable of performing positioning based on a plurality of satellite positioning systems, the method comprising:

acquiring given support information which is referred to in selecting a satellite positioning system; and

selecting a satellite positioning system which is used in positioning from the plurality of satellite positioning systems, on the basis of the support information.

2. The selection method according to claim 1, wherein information of a location at which the positioning device is located is at least included in the support information, and

the selecting includes selecting a satellite positioning system which is previously associated as a satellite positioning system available for positioning at position indicated by the location information.

3. The selection method according to claim 2, wherein the acquiring includes acquiring the support information including the location information from an external device capable of communication with the positioning device through near field communication.

4. The selection method according to claim 1, wherein the acquiring includes performing communication with an external device capable of performing positioning based on the plurality of satellite positioning systems, and acquiring positioning collateral information when the external device performs a positioning process, as the support information.

5. The selection method according to claim 4, wherein the positioning collateral information includes at least one of identification information of a satellite positioning system used by the external device, the number of satellites according to a satellite positioning system captured by the external device, identification information of a satellite captured by the external device, and orbit information of the satellite captured by the external device.

6. The selection method according to claim 4, wherein the selecting includes setting an order of priority of the satellite positioning systems that make an attempt at positioning, on the basis of the positioning collateral information.

7. A positioning device capable of performing positioning based on a plurality of satellite positioning systems, the device comprising:

a processor adapted

to acquire given support information which is referred to in selecting a satellite positioning system; and

to select a satellite positioning system which is used in positioning from the plurality of satellite positioning systems, on the basis of the support information.

8. A program causing a computer capable of performing positioning based on a plurality of satellite positioning systems to execute:

acquiring given support information which is referred to in selecting a satellite positioning system; and

selecting a satellite positioning system which is used in positioning from the plurality of satellite positioning systems, on the basis of the support information.
