If the base's position is unknown, and the accuracy of the base
can be meter-level, then it is recommended to use command
POSAVE to setup the base, refer to the Log & Command
document for more about this command. Please note the base’s
position will be different after a power cycle even if the antenna is
installed at the same point if POSAVE command is input.
If you require a cm level accuracy of base and rover, then:
a. Configure the base receiver as a rover, receive RTK corrections
from a CORS nearby, this receiver can get cm-level accuracy
position.
b. Collect raw measurements for half an hour, process it with post
processing software or send the data to an online processing
web, e.g. OPUS, to get an accurate position.
