Ch 6 GPS/GNSS 55
3Diff The type of x you have. Three satellites are
required for a 2D x while four are required for a
3D x. 3Diff means an SBAS (WAAS/EGNOS/MSAS)
signal is being used for the GPS/GNSS solution.
PDOP A measure of accuracy. The lower the number,
the more accurate the x is.
Note: When you suspend the FC-500, the receiver is in a low
power mode to retain its almanac. When you resume the
FC-500, it takes a few seconds to get a x.
GPS/GNSS Settings
To view or make changes to the GPS/GNSS settings or set up
an external GPS/GNSS, press and hold the GPS/GNSS status
gadget on the Home screen to go to the control panel.
Select the programs port, hardware port and baud rate
(internal GPS/GNSS uses COM8 at 115200 baud), program
access, data format, NMEA sentences, satellite systems and
module settings (update rate, baud rage, lter).
Several applications can share the COM port setup as the
GPS/GNSS program port using the GPS/GNSS Intermediate
Driver (GPSID).
