Re: Usage of GNU Radio for small spacecraft

[Daniel Estévez]

Thank you to all who have contacted me regarding this. Luckily I have 
received a large number of replies, both by email and on some social 
media platforms, so I have not been able to reply one by one.

I have now written a draft of the revised section about GNU Radio for 
this report, and in one week we will be sending this to NASA. I have 
posted the draft in the #satcom channel in the GNU Radio Matrix chat in 
case anyone wants to give feedback before the deadline:

https://chat.gnuradio.org/#/room/#satcom:gnuradio.org

The paragraph for which I was collecting example use cases reads as 
follows. As I mentioned, it is quite general, but it seems a good 
summary of all the information I have received.

"
In the small satellite industry, GNU Radio is frequently used as part of 
the ground station, both for standard protocols such as CCSDS and for 
custom modems. Some commercial groundstation-as-a-service solutions that 
support GNU Radio modems are Azure Orbital Ground Station and AWS Ground 
Station. Another example is the open-source community-driven SatNOGS 
network. GNU Radio is also very useful for prototyping and lab testing. 
Additionally, some small satellites run GNU Radio on-board, usually as 
part of a highly flexible SDR payload.
"

Best,
Daniel.
