A position calculating method performed by a position calculating device carried with or mounted on a mobile body and moving with the mobile body, includes: receiving a positioning signal from a positioning satellite; calculating a position based on the received positioning signal; intermittently operating a sensor unit which detects moving condition of the mobile body in predetermined intermittent operation cycle; controlling the intermittent operation cycle according to the positioning signal receiving condition; calculating a position by executing predetermined inertial navigation calculation by using a detection result from the sensor unit operated in the intermittent operation cycle; and determining an output position by using the position calculated based on the positioning signal and the position calculated by the inertial navigation calculation.
