Carrying out Kinematic and Stop & Go measurements, contd.

If you want to pick up subsequent

discrete points then just move to the

next point you want to measure.

Then press F1 OCUPY, and hold

your antenna steady for a few

seconds. You have to remain on the

point until at least one epoch of

"Static observations" has been

recorded. You can then again press

F1 STOP and F1 STORE to

complete the point measurement. A

Point Id and antenna height must be

entered for such Stop & Go points.

Post-processing will provide results

with point id's and associated

coordinates.

Make sure you avoid obstructions

when you move from point to point.

Severe obstructions might cause a

complete loss of lock which in turn

will cause a loss of accuracy in post-

processing. A static reinitialization will

become mandatory in such a case. A

warning message will be displayed to

inform the user to start another

"chain" of measurements:

"Another static initialization is

necessary"

In this case logging of raw data stops

automatically. Thus you now must

carry out another static initialization

(see above).

You are now ready to move your

antenna. You can expect coordinates

with centimeter accuracy as long as

lock to a minimum of 4 to 5 satellites

is maintained.

Observations are logged while

moving, which is indicated by a

switch in the status symbol from

"Static" to "Moving":

If you are only interested in the

trajectory of your antenna, then just

get moving. Postprocessing will

provide you with time tagged

coordinates for every epoch at which

observations are logged (normally

every 2, 3 or 5 seconds).
