Tip: RTCM1104b message is defined by ComNav Technology, which may be incompatible with
rover receiver of other brand.
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.
