(6) Fix Mode
•You can set the geodetic mode of the GPS/DGPS sensor.
•Press the up or down to select FIX MODE and push it in to
open the FIX MODE setting pull-down menu. Press the to
the left or right to select 2D, 3D or AUTO. When the GPS100 is
connected, 3D provides more precise data than 2D. When the
DPGS200 is connected, the AUTO mode is selected regardless of this
setting.
(7) HDOP Level
•You can set the upper limit of the HDOP level using this item. The
HDOP level indicates the geodetic precision determined by the
constellation of the GPS satellites. Precision is increased as this level
decreases and vice versa. The constellation of the GPS satellites
changes constantly and the HDOP level changes accordingly. The
GPS/DGPS sensor stops positioning when the HDOP level exceeds
the upper level specified in this item. Therefore, if you set a smaller
value as the upper limit, the precision is improved, but the possibility
of interupting positioning becomes larger.
•Press the
up or down to select HDOP LEVEL and push it
in to open the HDOP LEVEL setting pull-down menu. Press the
to the left or right to select 4, 10 or 20.
(8) Average
•You can set an interval to average the positioning data using this item.
If you set a longer interval, the positioning data becomes more stable.
If you set a shorter interval, you can reflect your vessel’s movement
changes more quickly, though the positioning data becomes less
stable.
•Press the
up or down to select AVERAGE and push it in to
open the AVERAGE setting pull-down menu. Then, select 40 sec, 10
sec or AUTO.
(9) Exclude Satellite No.
•Using this item, you can set the satellite numbers so that excluded
satellites are not used for positioning. The GPS/DGPS sensor does
not use these excluded satellites for positioning.
•Press the
up or down to select EXCLUDE SAT and push it
in to open the EXCLUDE SATELLITE NO. setting pull-down
menu. Press the up or down to set the satellite numbers
which should not be used while pressing the to the left or
right to move the setting frame. You can specify up to 6 satellite
numbers.
