1. A positioning apparatus comprising:
- a position computing part configured to receive signals from a plurality of radio transmitters to compute a position of the positioning apparatus;
a reception status determining part configured to determine a reception state of the signals from the plurality of the radio transmitters; and
an intermittent drive setting part configured to set a time interval for receiving signals by the position computing part according to the reception state determined by the reception status determining part,wherein the intermittent drive setting part shortens the time interval for receiving signals as the number of the radio transmitters from which signals can be received in the plurality of the radio transmitters is larger.

9. A positioning method comprising the steps of:
-
receiving signals from a plurality of radio transmitters to compute a position of an positioning apparatus; determining a reception state of the signals from the plurality of the radio transmitters; setting a time interval for receiving the signals according to the reception state; and reducing the time interval for receiving signals as the number of the radio transmitters from the plurality of the radio transmitters increases.
