8 RTK Mapping
Starting the base station
When you have assembled the base station, you must configure and
start it. Use the Asset Surveyor software to do this. Alternatively, if
you are using a Series 4000 receiver, you may want to start the base
station directly from the receiver’s front panel. If you choose the latter
option, refer to your Series 4000 documentation for details.
To start the base station using the Asset Surveyor software:
1. Start the Asset Surveyor software.
2. Select Data collection / Create base file.
3. The Antenna options form appears. Enter the antenna height,
antenna type, and measurement method. If you are using a
compact L1/L2 antenna with a ground plane, the antenna type is
‘Compact L1/L2 w/GP’. \ Press when you are done.
Note – Enter an accurate antenna height for the base station. If
the height is inaccurate, RTK data collected with reference to
the base station may be erroneous, especially in terms of the
vertical coordinate. For more information on measuring
antenna heights, see Antennas, page 204.
4. The Reference position form appears. Enter the position of the
known point manually, or select a waypoint that is at the correct
position. \ Press when you are finished.
The Real-time base station status form appears, indicating that
RTK corrections are now being generated by the receiver and
broadcast over the radio-modem link. As a check, you may hear
a regular signal being broadcast from the radio, or a light may
flash to indicate that signals are being broadcast.
5. Detach the TSC1 cable from the back of the base receiver.
