ABSTRACT:
A position identification apparatus includes a storage section storing a position-unique information database containing, each position on a field and unique information generated from the signal strength of the reflected wave at the position in association with each other, an ultrasonic transmission section originating an ultrasonic wave assigned identification information, an ultrasonic reception section receiving the reflected wave of the ultrasonic wave, a unique information generation section generating signal unique information from the reflected wave, and a position identification section making a comparison between the signal unique information generated by the unique information generation section and the unique information included in the position-unique information database and identifying the current position.
