For SBAS (L1C/A) signals each reported subframe contains eight 32-bit data words to deliver the
250 bits transmitted in each SBAS data block.
The eight words are arranged as follows:

3.12.1.7 QZSS
The structure of the data delivered by QZSS L1C/A signals is effectively identical to that of GPS
(L1C/A). Similarly the structure of the data delivered by the QZSS L2C signal is effectively identical
to that of GPS (L2C).
