Abstract:
1. A portable position acquisition apparatus, comprising: a position detection unit that acquires position information pertaining to said position acquisition apparatus, said position detection unit including at least a GPS receiver, and the position information acquired being based at least in part on information received by the GPS receiver; a memory that stores the position information; a battery for providing power to said position acquisition apparatus; a controller operatively connected to said position detection unit, said memory and said battery, and said controller determines a position change amount based on the position information and previously-transmitted position information, compares the position change amount to a threshold amount, and determines when said position detection unit should reacquire the position information based on at least the position change amount; and a communication interface that enables said position acquisition apparatus to transmit data to a remote device via a wireless channel, wherein the data being transmitted includes at least the position information, wherein said communication interface is controlled to transmit the position information to the remote device if the controller has determined that the position change amount exceeds the threshold amount, wherein at least one user setting is set from a remote location via a web interface, and wherein said controller causes said position detection unit to reacquire the position information dependent on the at least one user setting.
