[amsat-bb] ARISSat 1 & Funcube Telemetry Question: DBPSK vs BPSK

[Iain Young, G7III]

Hi All,

Just a quick clarification needed by me on the Telemetry format that is
going to be used by ARISSat-1 and Funcube (& I guess the Funcube boards
onboard UKube-1...)

Lots of places are referring to it as BPSK1000, but I have seen
references claiming it is DBPSK. Can someone clarify if it is
Differential BPSK, or "just" plain old BPSK as used before, but at 1000
BPS, rather than 400 ?

Reason for asking is that I have a USRP, and use gnuradio, along with
the gnuradio-companion. That has DBPSK blocks built in, but pure BPSK
would take a little more work (possibly just routing the output to a
loopback soundcard, and then running decoding software)
