Step 4:

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.
