Ending a kinematic and stop & go
operation.
End a kinematic or stop & go survey
by pressing SHIFT F6 QUIT. This will
of course also end logging of raw
data.
Initialization on a known point
You can now start moving and
occupy subsequent points with few
seconds of measurements. The
need for another static initialization
arises only in case of a complete
loss of lock, although it is
recommended to keep such a
"track" of measurements short
(e.g. maximum of 20 points).
When you post-process the data in
SKI-Pro you have to mark such
tracks as "Init (track)"; this ensures
that SKI-Pro relies on the already
existing coordinates for this point to
fix ambiguities. Again, it is important
that the coordinates of the starting
points are accurate to within 5 to 10
cm within the WGS84 system.
This method of initialization is of
particular interest for SR510 sensors
because static initializations on
unknown points are very time
consuming with single-frequency
receivers.
Static initializations can be speeded
up by occupying a point with known
coordinates.
If the coordinates of a point are
known in the WGS84 system to
within 5 - 10 cm, the static
initialization can be accomplished
with about 20 to 30 seconds of
measurements (10 to 15 epochs).
Get into the main Survey panel
Start measuring by pressing F1
OCUPY in order to log
observations on that point. Keep
the rangepole steady !
After about 20 to 30 seconds press
F1 STOP.
Make sure you enter the correct
point id and antenna height. Then
press F1 STORE.
