6. A Look at the Home Screen
6.6 GPS
If your Navi appears to be unstable, please check the satellite acquisition signals received by the GPS
antenna; tapping into the " GPS" menu and resetting the GPS status may help you to rectify the
situation.
Once you get into the second screen, you will find something like a GPS dashboard. There, ' State' gives
the overall performance of the GPS antenna in terms of acquiring satellite signals, where V means
failure and 2D/3D means success. ' Satellite' tells you which satellite signals are acquired (by the
device' s antenna) from all that are available. PDOP is an abbreviation of Positional Dilution of Precision,
HDOP of Horizontal Dilution of Precision and VDOP of Vertical Dilution of Precision. The numerical
values for these three are literally ' the smaller, the better' . At the bottom, you can see cells with unique
numbers in them, which represent the respective satellites, and graphic bars with figures below them,
which show the current detailed status in obtaining a signal from each satellite. If you want to start
afresh, tap the Reset button. The GPS antenna will start all over again. When you change of area, it is
recommended to press on the reset button.
