Hi Justin,
Good thoughts and suggestions.
We have aloso elborated on the same thought "downlink data
sharing from USRP for learning"
A USRP1 was donated to us for GOES LRIT reception
investigation. We hoped that students world wide would hook on to the
project but not even one was (or has sofar been) interested.
Tools available:
- full control of the receiver, VNC, ssh, ftp,
etc connection. Antenna twek/realigment withing 5h.
- *big dish* pointed at what ever is possible (GOES
E/W)
The result of this project sofar:
- no interest what so ever to receive *real time* signals
from a remote source and help GNU Radio. When I say remote signal source we
mean > 800 km (GOES 35000 km).
It seems like <10 m is more interesting today, I wonder
why...?
- our project was totally free for users (private money
used), of cource you had to ask for permission to enter (void junk) by
email
- who learned something from the data received? A Czech
and a Finn living ~9000 km away from the USRP and the antenna located at Los
Angeles. Many thanks for that!
Conclusions:
- universities like it when it cost alot (free help is
unacceptable)
- RX and TX must be < 10 m away. If there is a uSec
delay, blame USRP and GR. It is not ever your fault, of
cource.
- I could go on and on...
This is the trend I have noted (and I follow every
email) from GR since we started in 2008.
Just a consideration for those who *cry* when they
have a USRP RX/RX < 10m away, study harder!
Patrik
