GPS Status
The GPS Status command opens a GPS Status Screen which provides
information on the satellite signals that your iWAY is monitoring to
determine your position. You can access the GPS Status Screen by
choosing
GPS STATUS from the Options Menu. A screen like the one in
the following image will appear.
The iWAY GPS Status Screen. The GPS Status Screen contains several
graphical elements that represent a lot of information.
Current Position Lock
Three buttons along the left side of the GPS screen indicate the quality
of the units position lock. The button that's selected indicates your cur-
rent position lock. If none of them is selected your current position has
not been established.
2D means the iWAY has achieved a lock on your current position on a
map. A 2D lock does not include your altitude. The iWAY must receive
reliable signals from 3 satellites to establish a 2D lock.
3D means the iWAY has achieved a more reliable lock, including not
only your coordinate location but also your altitude (or elevation). The
iWAY must receive reliable signals from 4 satellites to establish a 3D
lock.
