Setting up as a Real-Time Base
Use
The equipment setup described is used for real-time base stations with the need of
optimal radio coverage. Raw observation data can also be collected for post-
processing.
Description
The GS10/GS25 instrument clips to the tripod leg. Connections are made to the GNSS
and radio antenna. The radio antenna is mounted on the antenna arm which clips to
the GNSS antenna. The GS10/GS12/GS14/GS15/GS25 instrument can be programmed
with the CS field controller before use which can then be omitted from the setup.
The GS10/GS25 instrument can be used as a DGPS base station, if fitted with the DGPS
option, and as a real-time base station.
The connection between GS14/GS15 and CS field controller is made via Bluetooth.
• The antenna is mounted directly using screw fitting. If using stub and adapter,
procedures can vary slightly.
• When using the adapter and carrier, ensure that the antenna and the adapter
assembly slide down the full length of the carrier stub. An incorrectly mounted
antenna will have a direct effect on the results.
• Standard radio is used throughout the instructions. Digital cellular phones can also
be used but the setup can differ slightly.
If the instrument is left in the container during use in high temperatures, the lid should
be left open. Refer to the User Manual for operating and storage temperatures.
Use an external battery such as GEB171 to ensure operation for a full day.
