Refer to the u-blox ZED-F9T Interface Description [2] for information about further
settings.
By default the ZED-F9T outputs NMEA 4.10 messages that include satellite data for all GNSS bands
being received. This results in a higher-than-before NMEA load output for each navigation period.
Make sure the UART1 baud rate being used is sufficient for the selected navigation rate and the
number of GNSS signals being received.
3.1.4 Basic receiver configuration
This section summarizes the basic receiver configuration most commonly used.
3.1.4.1 Communication interface configuration
Several configuration groups allow operation mode configuration of the various communications
interfaces. These include parameters for the data framing, transfer rate and enabled input/output
protocols. See Communication ports

3.1.4.2 Message output configuration
The rate of NMEA and UBX protocol output messages are configurable.
If the rate configuration value is zero, then the corresponding message will not be output. Values
greater than zero indicate how often the message is output.
For periodic output messages the rate relates to the event the message is related to. For example,
the UBX-NAV-PVT (navigation position velocity and time solution) is related to the navigation epoch.
If the rate of this message is set to one (1), it will be output for every navigation epoch. If the rate
