The positioner which includes absolute positioning mode and relative positioning mode, method, and the program

摘要

This invention regards, using the absolute positioning system and the relative positioning system, in order to decide position, the positioner which is formed (PD). The positioner is formed using the relative positioning system depending upon the absolute positioning system, and case using the absolute positioning system depending upon 1st mode, and the relative positioning system and the case where it decides position in order to operate with the 2nd mode which decides position. The absolute positioning system 2nd in mode compared to from is put emphasis in 1st mode, the positioner is formed, in order to change to 2nd mode from 1st mode. The positioner (PD) the digital map database (DMD and 3DMD) to access is possible, change to 2nd mode is decided from 1st mode on the basis of the position where it is decided at least the map database (DMD and 3DMD) combining with the information which is housed.
