GNSS System: Select the satellite systems you want to use
„
(GPS, SBAS, GLONASS) and module settings (update rate,
baud rate, filter). The GNSS receiver can be set to remain
on during suspend. This reduces satellite reacquisition time,
but also draws more battery power when suspended. You
might want to restart the GNSS receiver after changing
settings.
GPS Intermediate Driver
The GPS Intermediate Driver (GPSID) is used to allow more
than one program to use data from the GPS receiver. The
GNSS control panel controls how the GPSID is used. 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 GNSS program port and defaults to COM2. This
can be set up on the Programs screen of the GNSS control
panel.
Internal GPS is on COM8 and communicates at 115200
baud. These settings are found on the Hardware screen of
the GPS Settings control panel. If another GPS receiver is to
be used, this is where you connect that GPS receiver so that
the GPSID can access it.
The camera, GPS function and JSNav application use the
GPSID to obtain GPS information. Turning off the GPSID
through the GPS hardware port disables these functions.
Note: If an application accesses the GPS module directly
on COM8, the GPSID will not have access to the GPS,
preventing camera geotagging and GPS from functioning.
