| Abstract: | This paper discusses the relationship between station latitude and location precision under the ideal condition. Through computing the coordinates of some station in different latitude, we draw the conclustion that with the latitude rising the location precision reducing, and explain the phenomenon of location precision of west eastward higher than that of north southward. |
