Correction usage
If the user selects the Nearest checkbox, the rover will use differential corrections transmitted by
the nearest reference station. The checkbox corresponds to the receiver parameter
/par/pos/cd/mult/nearest.
When working in the Nearest mode, make sure that the checkboxes Mix and
Best are unchecked.
The Mix checkbox allows the user to run the rover station in ‘average’ mode.
The checkbox is associated with the receiver parameter /par/pos/cd/mult/mix.
When the rover runs in this mode, the Best checkbox must be unselected.
With the radio buttons Corrections and Positions, the user specifies which of the averaging
modes will be used for position computation. If both the Mix checkbox and Corrections radio
button are selected, the rover will be averaging differential corrections received from different ref-
erence stations. If the user selects the Mix checkbox and Positions radio button, the receiver
will average the computed positions, not the received corrections. These radio buttons correspond
to the receiver parameter /par/pos/cd/mult/mixmode.
If the Best checkbox is selected, the receiver will use differential corrections that correspond to
the most precise of the obtained position estimates.
Best
means that the solution has the least RMS
error. The Best checkbox is associated with the receiver parameter /par/pos/cd/mult/best.
In the CD Corrections max. age edit box, the user can set the maximum age (in seconds)
of the code differential corrections used for position computation. Here one can enter an integer
value between 1 and 1200. The default is 30. If the age of the corrections exceeds the value speci-
fied in this edit box, the rover will compute a stand-alone position. The edit box relates to the re-
ceiver parameter /par/pos/cd/maxage.
Use the Iono Corrections max. age edit box to specify the maximum age (in seconds) of
the ionosphere corrections used for position computation. The corresponding receiver parameter is
/par/pos/cd/iono/maxage.
If you set the Use Iono Corrections checkbox to ‘on’, the rover receiver will use in position
computation both the ionosphere corrections from RTCM message type 15 and differential correc-
tions from RTCM message types 1 and 31 (or 9 and 34). This checkbox is associated with the re-
ceiver parameter /par/pos/cd/ionofree.
The list box Source serves to specify the source (port) from which the receiver will use differen-
tial corrections for position computation. This list box relates to the receiver parameter
/par/pos/cd/port.
The receiver uses this parameter only if Multi-base mode is unchecked.
