PRN Search Mode Change between Automatic or Manual search mode.
In Manual search mode, the R4 Navigation sensor will
try to acquire signals from satellites with id (PRN)
numbers input by the parameters PRN 1 and PRN 2 in
the view. If only one particular satellite is to be tracked,
input same number for both parameters.
In Automatic search mode, the R4 Navigation Sensor
will try to identify and track SBAS signals without user
control of satellite selection.
PRN 1 (Primary) The PRN of the primary satellite that should be used
when operating in Manual PRN Search Mode.
PRN 2 (Secondary) The PRN of the secondary satellite that should be used
when operating in Manual PRN Search Mode.

Parameter Name Description
Tuning Mode The Tuning Mode parameter sets the frequency
selection mode of the R4 DGPS Navigation Sensor
internal radio beacon receiver. The mode can be
Frequency Scan, Manual or Database (Auto). The
Database mode is only available when the Beacon
Database is enabled.
In Frequency Scan mode, the beacon receiver will
search available frequencies and tune to the strongest
beacon signal. In this mode, the R4 Navigation Sensor
continuously performs background search to discover
higher quality DGPS signals. While performing
background searches, the R4 Navigation Sensor
continues to receive differential corrections from the
current radio beacon station.
In Manual tuning mode, the R4 DGPS Navigation
Sensor tunes to the specified beacon frequency for
receiving DGPS signals.
In Database mode, the receiver will search for the
closest station based on its current location and
distance to the internal list of station locations. The
frequency and bit rate specified in the station database
will be used and therefore these parameters are hidden
when the Tuning Mode parameter is set to Database
(Auto).
Frequency (kHz) The Frequency parameter is used to set the frequency
to use for receiving DGPS Beacon signals, when the
