Qualche considerazione di Jim Lux, un ingegnere delle comunicazioni della NASA che spesso e volentieri commenta sulla lista Amateur_DSN. Penso sia un buon punto di vista per capire perchè non sarà possibile tentare un recupero di ICE:
"I think there’s more to this story than what’s in the blog. We talk to
spacecraft with fairly simple modulations: BPSK data on a subcarrier
that is then phase modulated onto a carrier. And it’s not like we don’t
have the capability to radiate at S-band (although not from Madrid,
Certainly, some software or FPGA solution could be cobbled up to
generate the right bits at the right time, even if back in the 70s, this
was done in dedicated hardware. The same applies on the receiver side.
Something that could probably be done in a USRP in a week or so.
Assuming you have a box sitting in front of you that can send and
receive the bits, there’s a fair number of procedural steps before you
can legally radiate (compatibility testing, etc.). There’s also a fair
number of administrative steps involved (e.g. who’s going to pay for the
time on the dish and the staff involved).
This is all doable, but it’s also probably in the several hundred
thousand dollar range by the time you’re done.
It’s kind of like saying, “the train tracks are there, and I know how to
drive a train engine from reading some books about it, can I just borrow
a train for a day and go from point A to point B? I’ll pay for the fuel.”
The cost of the fuel for the train is insignificant compared to all the
other things that need to be done."
Ciò detto, ho scritto a qualche guru per avere i dati orbitali, vedremo.
