3.1.4.2 Message output configuration
The rate of the supported output messages is 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
is set to two (2), it will be output every other navigation epoch. The rates of the output messages
are individually configurable per communication interface. See the CFG-MSGOUT-* configuration
group.
Some messages, such as UBX-MON-VER, are not periodic and will only be output as an answer to
a poll request.
The UBX-INF-* and NMEA-Standard-TXT information messages are non-periodic output messages
that do not have a message rate configuration. Instead they can be enabled for each communication
interface via the CFG-INFMSG-* configuration group.
All message output is additionally subject to the protocol configuration of the
communication interfaces. Messages of a given protocol will not be output until the protocol
is enabled for output on the interface (see the previous section).
3.1.4.3 GNSS signal configuration
The GNSS constellations and bands are configurable with configuration keys from configuration
group CFG-SIGNAL-*. Each GNSS constellation can be enabled or disabled independently. A GNSS
constellation is considered to be enabled when the constellation enable key is set and at least one
of the constellation's band keys is enabled.
ZED-F9P only supports certain combinations of constellations and bands. For all constellations,
both L1 and L2 bands must either be enabled or disabled. BeiDou B2 is the exception (can either
have BeiDou B1+B2 or B1-only). Unsupported combinations will be rejected with a UBX-ACK-NAK
and the warning: "invalid sig cfg" will be sent via UBX-INF and NMEA-TXT messages (if enabled).
The following table shows possible configuration key combinations for the GPS constellation.
