177 7. Measuring with System 500 Technical Reference Manual-4.0.0en
You will need to select the way in
which you define the reference point.
You may select either a known point
from the drop down list or use the
LAST (F3) key to use the coordinates
that were used when the sensor was
last used as a reference station.
Alternatively, use the HERE (F4) key
to select the present navigation
position or use the Single Point
Positioning SPP (F6) feature to
determine the reference point.
7.3.1 Measuring procedure
Using a known point
Select a point from the drop down list
box. This point will have been
previously entered into the database
manually, from SKI Pro, or may be a
point resulting from a previous real-
time rover measurement.
Use the COORD (F2) key to switch
display between coordinate systems.
Measure and input the Antenna
Height (Ant Height). When using a
Tripod this will be measured using the
Height Hook.
Further details on measuring the
Antenna height can be found in
section 2.15.
Using the last used Reference
Station coordinates
To use the same coordinates that
were used when the sensor was last
used as a reference station, choose
LAST (F3).
When a sensor is used as a
reference station and is turned off, the
reference station coordinates are
stored within the System RAM. They
can then be used again the next time
the sensor is used as a reference
station.
This means that even if the PC card
that previously contained the
reference station coordinates is
formatted, the last used coordinates
can still be used.
