Advance Information
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 the answer to
a poll request.
The UBX-INF-* 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 previous section).
4.3.3 GNSS signal configuration
Several configuration items govern the use of GNSS signals and constellations. Each GNSS
constellation can be controlled separately. Similarly, each signal within the constellation can be
handled independently of each other. The constellation enable master keys and their associated
signal enable keys are linked such that a GNSS constellation is considered enabled if and only if the
master constellation enable key is set and at least one signal associated with that constellation is
enabled.
This dependency allows the user to disable a constellation without having to disable each signal on
its own. The signal enable keys give users the flexibility to enable or disable each signal separately
if they need to. See figure below which describes the flow of enabling / disabling a constellation.
