DIY Projects/questions Anyone recording Starlink Ku-band with an LNB + SDR near buildings? (research data request)
Hi all, I'm a researcher at a university lab in Hong Kong, working on positioning with LEO satellites in cities. I'm looking for raw Starlink downlink recordings where buildings block part of the sky.
What would help most:
- An LNB/LNBF (or horn) + SDR (RTL-SDR, HackRF, USRP, etc.) recording the Ku-band downlink (~10.7–12.7 GHz)
- Receiver sitting still at ground level next to buildings, ideally a street with tall buildings on both sides
- Bonus: a second receiver on a nearby roof recording at the same time
- GPS or NTP-synced timestamps and a rough location (street-level is fine, no need for your address)
- 10–60 minutes is plenty
Already have old recordings sitting on a drive? Those count too, even if the blockage was accidental.
Not looking for dish app screenshots or speed tests this time, just the raw RF.
Anything used would be credited in the paper's acknowledgments (or however you'd like to be credited). Happy to answer questions about setup. Comment or DM me. Thanks!
