4 SBF Reference
The default output rate is specified for each block in chapter 4.2. To instruct the receiver
to output a given block at its default rate, the "
OnChange
" rate has to be specified in the
command.
Some blocks can only be output at their default rate (e.g. the
block). Others can be
decimated to a user-selectable rate. A subset of blocks can also be output "once" using the
command. This can be handy to get a one-shot overview of a particular receiver
state. Whether a given block supports a user-selectable rate (“Flex Rate”) and whether it
belongs to the "output once" set is indicated in the SBF block list in Appendix A.
Attempting to force another rate than the default one for those blocks that do not support
“Flex Rate” has no effect: those blocks are always output at their default rate.
4.1.9
Satellite ID and GLONASS Frequency Num-
ber
Satellites are identified by the
(or
) and
FreqNr
fields, defined as in the table below.
This table is only valid for the currently-supported constellations and signal types (see 4.1.10).
To ensure compatibility with future SBF upgrades, decoding software must ignore SBF blocks
and sub-blocks of which the satellite ID field or the signal number field is undefined in this
document.

71-106: PRN number of a GALILEO satellite with an offset of 70
Enn
(
nn
= SVID-70)
107-119: L-Band (MSS) satellite. Corresponding satellite name can be
found in the
LBandBeams
block.

Cnn
(
nn

FreqNr
u1
0
GLONASS frequency number, with an offset of 8. It ranges
from 1 (corresponding to an actual frequency number of
-7) to 21 (corresponding to an actual frequency number of
13).
For non-GLONASS satellites,
FreqNr
is reserved and
must be ignored by the decoding software.
