Output GPGGA message to check if OEM board is in SBAS mode, solution status should be “E,2” (SBAS mode)
and base ID should be SBAS satellite’s PRN, such as “0129”.

Generally, RTK mode is a commonly used work mode, which can provide centimeter real-time positioning
accuracy. We recommend using RTCM3.0/3.2 as correction data, please refer to following configuration to
start RTK mode.

With 9600 baud rate for air link, the limited number of data can be sent out per second in radio mode.
Therefore, it’s better to set latency time for different constellations if you start base station in radio mode.
The following commands show RTCM3.0 as an example, which may be incompatible with rover receiver of
other brands.
