RTCM2Words
u4[
N
]
30-bit words of the RTCM2 message. The Data Word Length (number of
32 bit words) is variable and depends on the RTCM2 message contents.
It can be computed by the following piece of C code:
N = 2 + ((RTCM2Words[1]»9) & 0x1f);
N
can range from 2 to 33. The first two words are the RTCM2
message header and they are always present.
Each of the words is organized as follows:
Bits 0-5:
6 parity bits. They are provided for the sake of completeness.
Parity doesn’t need to be checked, since the
block only contains valid words.
Bits 6-29: 24 information-containing bits of the word. The first received
bit is the MSB.
Bits 30-31: bit 0 and 1 of the preceding word
If the
