4 SBF Reference
RFStatus
Number:
4092
"OnChange"
interval: 1s
The
block reports on the quality of the radio-frequency (RF) signal received by
the antenna(s). The
RFBand
sub-blocks provide a list of the frequency bands where interfer-
ences have been detected and/or mitigated, and the
Flags
field contains warnings that the
receiver’s output may be affected by non-authentic RF signals.

Bit field:
Bit 0:
Set when the receiver determined that its output (position or raw
measurements) may be affected by a spoofer, and may there-
fore be misleading. This bit is based on a set of built-in tests to
check the authenticity of the GNSS signals. Note that this bit may
be set even if no interference is detected (i.e. with no associated
RFBand
sub-blocks).
Bit 1:
Set when spoofing is detected by Galileo OSNMA.
Bits 2-7: Reserved
