This list is probably as good as any other on this topic,
though you might want to also try our "gpstech" list (general
GNSS topics to a slightly broader list).

AFAIK, the only Trimble receivers that have BINEX as an
output option are the 4700 (used in the UCAR SuomiNet
project) and the NetRS -- though for the latter is still
in a development/verification stage for EarthScope/PBO.
For the 4700, the SNR was recorded in BINEX 0x7f-02 to the
nearest 0.25 dBHz; for the NetRS it will recorded in BINEX
0x7f-03 to the nearest 0.1 dBHz.

Brian Frohring or someone else at Trimble might want to
comment further.
