ASUS r300 빠른 설정 가이드

The GPS receiver uses satellite signals to calculate its (your) position and need at 

least four signals to give a three-dimensional position, including elevation. Because the 

satellites are moving and because objects can block the signals, your GPS device might 

not receive four signals. If three satellites are available, the receiver can calculate the 

GPS position but the accuracy is lower and the GPS device does not give you elevation 

data: only 2D reception is feasible.
In Asus GO, you can see the GPS position quality on the GPS Data Screen.
2D and 3D GPS reception have nothing to do with the 2D and 3D display modes of the 

map, which are ways of showing the map on the screen independently of the quality of 

the GPS reception.

The instructions used in the ongoing navigation. You can save and load routes in Asus 

GO, but at most one route is active at any give time, and it is always active until you 

delete it, reach your destination or you shut down Asus GO.
For information how Asus GO shows the active route on the map.

The City Centre is not the geometric centre of the settlement but an arbitrary point 

the map creators have chosen. In towns and villages, it is usually the most important 

intersection; in larger cities, it is an important intersection.
