Direction acquisition program, terminal and orientation acquisition method, validity map control program, validity map controller, and effective map control method

摘要

Problem to be solved: to provide an azimuth acquisition program, a terminal and an orientation acquisition method for obtaining an orientation well.Geomagnetic sensorTo the terminal equipped with the gyro sensor and the acceleration sensorObtaining position information indicating the position of the terminal andDetection result of said geomagnetic sensorDetection result of the gyro sensor andDetection result of the acceleration sensor andAndIf the position of the terminal indicated by the location information is not in the area where the geomagnetic sensor is valid, thenDetection result of the gyro sensor andDetection result of the acceleration sensor andThe orientation of the terminal is obtained based on the detection result of the geomagnetic sensor andAn orientation acquisition program to be executed is provided.Diagram
