7.8.2.1 CORRECTION METHOD
Set the correction method. When SBAS is selected, the GPS receiver must be compatible with SBAS.
GPS Single: Fix a position only with single GPS. Does not perform fixing with SBAS or beacon.
SBAS: Fix a position with SBAS or single GPS. Does not perform fixing with beacon.
Beacon: Fix a position with beacon or single GPS. Does not perform fixing with SBAS.
AUTO: The optimum setting is selected from single GPS, SBAS and beacon.
7.8.2.2 FIX MODE
Set the GPS fix mode.
2D: 2D positioning can be done with height acquired.
3D: 3D positioning can be done with height acquired.
AUTO: 2D positioning and 3D positioning can automatically be selected with optimum.
7.8.2.3 ELEVATE MASK
Limit the satellite to be used with elevation angle.
7.8.2.4 HDOP
Set the HDOP level of the GPS receiver.
The smaller the value, the higher the accuracy although fixing a position becomes difficult.
7.8.2.5 SMOOTHING LAT/LON
Smoothing can be applied to measured positions. The higher the smoothing value, the smoother the results
will be, but the greater the time lag. Conversely, if the smoothing value is set low, a great number of changes
will occur, but there will be little time lag. As such, it is important to choose the optimal value for own usage
situation.
7.8.2.6 SMOOTHING SOG
Smoothing can be applied to measured speeds. The higher the smoothing value, the smoother the results will
be, but the greater the time lag. Conversely, if the smoothing value is set low, a great number of changes will
occur, but there will be little time lag. As such, it is important to choose the optimal value for own usage
situation.
7.8.2.7 SMOOTHING COG
Smoothing can be applied to measured courses. The higher the smoothing value, the smoother the results
will be, but the greater the time lag. Conversely, if the smoothing value is set low, a great number of changes
will occur, but there will be little time lag. As such, it is important to choose the optimal value for own usage
situation.
7.8.2.8 SMOOTHING1
This setting is corresponding to relatively new JRC GPS model.
Note: The smoothing setting range is depending on the JRC GPS software version.
0 to 99 sec (R29.04~R33.99)
1 to 99 sec (R26.01~R29.03)
