11/12 SV The number of satellites currently in view followed

by the number of satellites used for the current

position.

3Diff

The type of fix you have. Three satellites are

required for a 2D fix while 4 are required for a

3D fix. 3Diff means SBAS (WAAS/EGNOS/MSAS)

signal is being used for GPS solution.

PDOP

A measure of accuracy. The lower the number, the

more accurate the fix is.

Note: When you suspend the Mesa, the receiver is in a low power

mode to retain its almanac. When you resume the Mesa, it takes a few

seconds to get a fix.

GPS Settings

Internal GPS uses COM7 at 38400 baud. To make changes to the

GPS settings or set up an external GPS, press and hold the GPS

status gadget to go to the GPS Settings control panel.

Several applications can share the COM port set up as the GPS

program port using the GPS Intermediate Driver (GPSID).
