Understanding what it is and how it works puts things into perspective and removes this and other misconceptions.＜/p＞ ＜p＞The book shows that it is no better than other systems, but, despite that it is a remarkable although complex system that has become a very convenient, mostly reliable and cheap way of getting around. When the limitations are understood, in GPS itself and in the map.＜/p＞ ＜p＞The aim is for gaining a higher understanding of how it works to enable you to get the best out of your system, avoiding confusion and being misled. You may find some of the ways it works surprising. 131 pages.＜/p＞画面が切り替わりますので、しばらくお待ち下さい。
