I'm guessing that you're exploiting some sort of exploit (buffer overflow???) on the DVB-T demodulator

The tech is already there, but the reason those antenna are not widely used is that they used to fall under ITAR, so no US companies want to touch those for civilian uses. Of course Turkey and China is not US so they don't give a damn

My thoughts as several things can be true at once: - This study is the source of LinkedIn ads from climate change where they try to convince people to move from gas to electric because of bad health effects - But it doesn't invalidate

That brings up some weird memories.. I saw 2 different researchers do bit manipulation in Matlab by printing the binary data as hexadecimal string, doing string manipulation on it and convert it back to binary

There's a strong indication that SpaceX does use software receiver in Falcon 9 and Starlink: when they didn't encrypt the downlink telemetry someone captured the signal and found some plain text: https://www.rtl-sdr.com

For L1 I think a raspberry pi can have a reasonably fast time to first fix, for offline processing you can go faster than real time. L2/L5 need large sampling rate and a pi is probably not fast enough.. unless if you ditch float32 proc

Because ITAR only applies to US companies, non-US companies can do and sell whatever they want. My favorite example is CRPA antenna, where they can block the jamming signal, so it was on ITAR. Other countries like Turkey and China doesn&#x2

A bit pedantic here.. I think you might be thinking about space tether propulsion. I don't know if that has been deployed yet. Magnetorquers, as in a device that uses magnets to rotate the satellite are very common in cubesats, you can

As someone that have successfully flown a RPi CM4 based payload on a cubesat, I fully agree with this. There's not enough funding in my research group to hire a dedicated test engineer so I need to both design and test my payload. It w
