Zusammenfassung:	PROBLEM TO BE SOLVED: To provide a correction factor arithmetic unit capable of acquiring highly accurate distance correction factors with high reliability by sufficiently utilizing sequentially captured GPS information. SOLUTION: Every time new GPS information is acquired, the current GPS information and past GPS information are selected in order of proximity to the current GPS information. Until the number of selected items of past GPS information reaches a prescribed number, the selection of past GPS information is further repeated to the current GPS information. If GPS information exists which is considered inappropriate for the computation of distance correction factors, learning is terminated. COPYRIGHT: (C)2007,JPO&INPIT
