BDSRawB2b
Number:
4242
"OnChange"
interval: 1s
This block contains the raw symbols of a BeiDou B-CNAV3 or PPP-B2b_I navigation frame, as
received from the B2b signal.
The receiver attempts to correct bit errors using the LDPC parity bits, but unrecover-
able errors are still possible at low C/N0. It is therefore always needed to check the CRC
status before using the navigation bits.

Status of the CRC check on the 486 bits of the message:
0:
CRC check failed
1:
CRC check passed
Reserved1
u1
Reserved for future use, to be ignored by decoding software.
Source
u1
Signal type from which the bits have been received, as defined in 4.1.10
Reserved2
u1
Reserved for future use, to be ignored by decoding software.
RxChannel
u1
Receiver channel (see 4.1.11).
NAVBits
u4[31]
NAVBits
contains the 984 symbols of a BeiDou B2b navigation frame.
Encoding:
NAVBits
contains all the symbols of the frame, exclud-
ing the preamble. The first received symbol (i.e. the MSB of the PRN
field) is stored as the MSB of
NAVBits[0]
. The 8 unused bits in
NAVBits[30] must be ignored by the decoding software.
