    • A GPS position calculating apparatus is configured to acquire from navigation data contained in signals transmitted from GPS satellites, orbit information including a position, clock time, orbital speed and altitude of each GPS satellite at a transmission time of each signal from a respective one of the GPS satellites, then calculate a position of each GPS satellite at a reception time of the same signal at a measurement point on the basis of the acquired orbital speed and a time difference between the reception time and the transmission time, further calculate a first angle of the horizon relative to a first line segment connecting the second position of each GPS satellite with a position of the measurement point on the basis of a range of the first line segment and the acquired altitude, subsequently calculate a range of a second line segment connecting the first position of each GPS satellite with the position of the measurement point on the basis of the range of the first line segment, the first angle, and the orbital speed, and finally perform calculation of the position of the measurement point. A GPS position calculating method carried out by the apparatus is also disclosed.
