Note 1: Set time is an internal 10 ms (T10) count since power-on initialisation enabled the processor interrupts. It is not used to
derive GPS time, but provides sequence of events knowledge. The T10 count references the receiver's internal time at which the
message was created for output. The T10 range is approximately 71 weeks.
Note 2: The sequence number is a count that indicates whether the data in a particular binary message has been updated or
changed since the last message output.
Note 3: If this bit is set, the receiver only uses 'perfect' measurements (i.e. without errors in tracking status or data). If the bit is not
set, measurements that are not perfect, but still good enough to use under SPS conditions, are used.
Note 4: The selected candidate list is a 32-bit flag, each bit representing candidate selection status for one satellite (ie bit 0 = SV1
status, bit 1 = SV2 status, bit 31 = SV32 status).
