Measuring procedure with starting
time
Switch on the instrument. Select
Survey. Select a Real-Time Rover
Configuration Set in which auto
occupy has been set to Timed in the
Occupation Settings.
During this time, the unit should
acquire satellites and should pick up
the signal from the Reference.
When enough of the same satellites
are tracked simultaneously at the
Rover and Reference and the signal
from the Reference is received, the
Receiver will automatically start the
ambiguity resolution process.
Note that if code only measurements
are being used, the ambiguity
resolution process is not required and
therefore will not start.
The line Start Time changes to
Time to go.
The time before the measurement
starts automatically is displayed in
hours:minutes:seconds and is
counted down.
Once the entered start time is
reached, the measurement beginns.
The icon changes to a tripod,
indicating that the Receiver should
remain stationary.
The ambiguity resolution process will
run. When the ambiguities are
resolved, the baseline from the
Reference to the Rover is calculated
to between 1-5cm.
The Accuracy Status Icon will be
displayed as follows:
Additionally, the Coordinate Quality
should show between 0.01 and 0.05.
To record a point, place and level the
pole. Input information such as Point
Id, Code (if required) and start time. If
working in Advanced mode, use the
ADD (F5) key to add point
annotations. Press the OCUPY (F1)
