In the
PDOP mask
edit box you specify the threshold value of PDOP that
disables position computation. If PDOP exceeds this mask during a period of time, the
receiver’s position will not be computed over the corresponding epochs. The associated
receiver parameter is
/par/pos/pdop
.
RAIM Enabled
•
If the
RAIM Enabled
checkbox is selected, the receiver automatically will detect
and reject measurement outliers. The corresponding receiver parameter is
/par/pos/raim/mode
.
•
The drop-down list box
Alarm
is associated with the receiver parameter
/par/pos/raim/al/mode
.
•
The
Alarm limit
edit box relates to the receiver parameter
/par/pos/raim/al/manual
.
From the drop-down list box
Current Datum
you select the datum used in position computa-
tion. This setting is associated with the receiver parameter
/par/pos/datum/cur
.
Pressing the
Datum Parameters
button will open the
<Datum ID> Datum
Parameters
window (Figure 29). In this window one cannot only
view the ellipsoid and trans-
formation parameters of the datums selectable from the
Current Datum
list box but also
edit
the transformation parameters for
USER
and
P90
. In addition the ellipsoid parameters of
USER
can
be edited in this window.

Positioning System
•
Select the checkboxes
GPS
and
GLONASS
if it is desired that the corresponding
satellite constellations to be used in position computation. These checkmarks are asso-
ciated with the receiver parameter
/par/pos/sys
.
Note, however, that the selected satellite constellation will indeed be used in position
computation
only if the corresponding
Satellites used in pos.
checkbox from the
Satellite management
panel is selected as well.
