gure the AsteRx-U MARINE Fg
for RTK
The AsteRx-U MARINE Fg can use correction data to calculate a cm-level RTK position. The
AsteRx-U MARINE Fg can get this correction data in several ways: using the build-in UHF
radio, over GSM/GPRS or Ethernet.
4.1.1 How to con

can be used to both receive and transmit data.
Step 1: Enable RTK mode
RTK should be enabled as a positioning mode. This can be done in the
GNSS, Position
