PROBLEM TO BE SOLVED: To improve the accuracy of measurement by autonomous navigation.SOLUTION: An electronic apparatus according to the present invention measures a position by a first positioning method that is executed intermittently and a second positioning method that is executed continuously. This electronic apparatus has a processor for calculating an angular difference formed by two line segments linking the position obtained by the first positioning method at a prescribed point of time and the position obtained by each of the first positioning method and the second positioning method at a point of time later than the prescribed point of time, determining a correction angle using the calculated angular difference and a gain that corresponds to the accuracy of positioning by the first positioning method, correcting the angle used in the second positioning method on the basis of the determined correction angle, and executing a process for estimating the travelling azimuth of the apparatus itself from the corrected angle.SELECTED DRAWING: Figure 2 |
