Bit field:
Bits 0-4: Signal type from which the bits have been received, as defined
in 4.1.10
Bit 5:
Set when the nav page is the concatenation of a sub-page re-
ceived from E5b, and a sub-page received from L1BC. In that
case, bits 0-4 are set to L1BC.
Bit 6:
Reserved
Bit 7:
Reserved

RxChannel
u1
Receiver channel (see 4.1.11).
NAVBits
u4[8]
NAVBits
contains the 234 bits of an I/NAV navigation page (in nominal
or alert mode). Note that the I/NAV page is transmitted as two sub-pages
(the so-called even and odd pages) of duration 1 second each (120 bits
each). In this block, the even and odd pages are concatenated, even
page first and odd page last. The 6 tails bits at the end of the even
page are removed (hence a total of 234 bits). If the even and odd pages
have been received from two different carriers (E5b and L1), bit 5 of the
Source
field is set.
Encoding:
NAVBits
contains all the bits of the frame, with the ex-
ception of the synchronization field. The first received bit is stored as
the MSB of
NAVBits[0]
. The unused bits in
NAVBits[7]
must be
ignored by the decoding software.
