GPS Intermediate Driver
The GPS Intermediate Driver (GPSID) is used to allow more
than one program to use data from the GPS/GNSS receiver.
The GPS/GNSS Settings control panel controls how the GPSID
is used. Internal GPS/GNSS is on COM8 and communicates
at 115200 baud. These settings are found on the Hardware
screen of the GPS/GNSS Settings control panel. If another
GPS/GNSS receiver is to be used, this is where you connect
that GPS/GNSS receiver so that the GPSID can access it.
The GPSID can output data on another COM port in a way
that allows multiple programs to access the same COM
port. This is called the Program Port and defaults to COM2.
This can be set up on the Programs screen of the GPS/GNSS
Settings control panel.
The camera, GPS/GNSS function and JSNav application use
the GPSID to obtain GPS/GNSS information. Turning off the
GPSID through the GPS/GNSS hardware port disables these
functions.
Note: If an application accesses the GPS/GNSS module
directly on COM8, the GPSID will not have access to the
GPS/GNSS, preventing camera geotagging and GPS/GNSS
from functioning.
GPS/GNSS Accuracy
The GPS/GNSS antenna is in the top of the Archer 2. Do not
put your hand or another object over the cap. This reduces
accuracy. The more items between you and the satellites,
the lower the accuracy.
