"GPS" is an abbreviation for Global Positioning System, which is a system for position determination by artificial satellites. "GPS satellite" refers to an artificial satellite used for position determination in GPS. "GP
The “S signal” refers to a signal transmitted from the GPS satellite 90 for position determination. In GPS, the position of the measurer is usually calculated from the distances from the GPS satellites 90 by GPS signals from at least four GPS satellites 90.

"Position data" means data representing the position of the measurer calculated from GPS signals, and is usually expressed by a combination of latitude and longitude. "Signal reception analysis means" means means configured by an antenna for receiving GPS signals, software for analyzing the GPS signals, and means for executing processing according to the software, such as a CPU. Then, the position data is to be calculated by this analysis. In addition,
The position data calculated by the signal reception analysis means 25 may be used for the processing as it is, or may be appropriately converted by the following means during the processing.

It may be sufficient that there is a closed portion where the start point and the end point do not match. Further, the coincidence between the start point and the end point may be regarded as coincident because both points are located close to each other even if they are not strictly coincident.
