Juniper Systems Mesa User Guide - Manual (Page 57)

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).
