Ch 6 GPS/GNSS 55
3Diff The type of x you have. Three satellites are
required for a 2D x while 4 are required for a
3D x. 3Diff means a SBAS (WAAS/EGNOS/MSAS)
signal is being used for the GPS solution.
PDOP A measure of accuracy. The lower the number,
the more accurate the x is.
Note: When you suspend the Archer 2, the receiver is in a
low power mode to retain its almanac. When you resume
the Archer 2, it takes a few seconds to get a x.
GPS Settings
Internal GPS uses COM8 at 115200 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).
