The SBAS Correction Source bit will toggle each time the SBAS PRN that is providing the corrections
(ionospheric or range) changes with respect to the last measurement block transmitted. The value
when the label is first transmitted (or transmission re-starts) with SSM at Normal Operation provides no
information on the correction source.
