Set Receiver to Self-Survey Approx. Coordinate for 60sec and Set It As Fixed Base Antenna
Coordinate Permanently
This setting is similar to 6-4-2 except self-survey will be performed immediately and the averaged
position will be used to set permanent base antenna coordinate. Afterwards powering up, Alpha will
use that antenna position coordinate for base antenna position reporting.

Using RTK Base Station to Determine Base Antenna Coordinate and Set It As Fixed Base
Antenna Coordinate
This setting uses public or private RTK base station service to determine base antenna position and set
it as fixed base antenna position. Below procedures need to be first performed on the to-be RTK base
Alpha receiver:
Change Alpha’s interface selection to Bluetooth
Put slide switch to position B
Connect Alpha to base station service via Android phone as described in section 6-4-2.
This prepares Alpha RTK receiver as 3
rd
-party base station connected RTK rover, able to determine its
position to centimeter-level accuracy. Have a USB cable connecting Alpha and RTK Viewer, we can now
select this 4
th
option to setup the Alpha RTK base antenna position. RTK Viewer will take 60 RTK Fix
position averaged value to set permanent base antenna coordinate. When done, put slide switch back
to position A for Alpha to function as base.
