NEO-F10N - Integration manual
Any change to the signal configuration items triggers a restart of the GNSS subsystem. During
the restart, the host application should wait for message acknowledgement and a margin of 0.5
seconds prior to sending any further commands.
For more information on the CFG-SIGNAL-* configuration group, refer to the Interface description

2.1.4 GPS L5 signal health status configuration
NEO-F10N supports both GPS L1 C/A and L5 signals. Broadcasting of Civil Navigation (CNAV)
messages on the L5 signal began in April 2014. At the time of writing, GPS L5 signals remain
which are set unhealthy until sufficient monitoring capability is established.
To evaluate GPS L5 signals before they become fully operational, the receiver can be configured to
ignore the GPS L5 health status by overriding it with the respective GPS L1 C/A signal status.
Do not use unhealthy, pre-operational GPS L5 signals for safety-of-life or other critical purposes.
This is an operational issue concerning the satellites / space segment and not a limitation or
specific configuration of u-blox products.
To ignore the GPS L5 signal health status and override it with the respective GPS L1 signal health
status, send the configuration string given in
. The configuration can be stored in RAM,
battery-backed RAM (BBR), and flash layers. Stored in the RAM layer, the device returns the UBX-
ACK-ACK message if the configuration is sent successfully and it is applied immediately without
a configuration reset. To apply the configuration stored in the BBR and flash layers, send the UBX-
CFG-RST message with resetMode 0x01.
To revert back to the default configuration, send the configuration string given in
. The
device returns the UBX-ACK-ACK message if the configuration is sent successfully and it is applied
immediately without a reset in the RAM layer. To apply the configuration stored in the BBR and flash
layers, send the UBX-CFG-RST message with resetMode 0x01.
Customers who choose to ignore the GPS L5 signal health status in their production system do
so at their own risk and must be fully aware of the implications. The system should also include
a mechanism to revert to the mode where the L5 signal health status is respected.

2.1.5 Communication interface configuration
Several configuration groups allow configuring the operation mode of the communication
interfaces. These include parameters for the data framing, transfer rate and enabled input/output
protocols. See
Communication interfaces and PIOs
