For the techy people - Boris Rozhin.
"Interesting details of the analysis dedicated to the fight against Starlink in Iran.
Active GPS spoofing - the terminal detected fake GPS signals (18 satellites visible, GPS is working, but disabled).
Effective countermeasure activation - anti-spoofing protection is activated using the inhibitGps flag.
Significant performance degradation - packet loss exceeding 20%, no stable connection, limited throughput.
Beam tracking degradation - pointing error is 3-4 times greater than position determination error.
Basic communication maintained - connection maintained despite electronic warfare.
Key takeaway: Although Starlink's anti-spoofing system is operational, GPS interference effectively reduces communication quality from broadband to virtually unusable.
The terminal remains online, but with:
Consistent packet loss of over 20%;
A connection that never stabilizes;
Limited bandwidth
; Suboptimal beam pointing.
This demonstrates that GPS spoofing/jamming is an effective tactic for degrading (but not completely eliminating) satellite internet service. SpaceX's backup positioning algorithms maintain communication, but are currently unable to ensure normal operation under these conditions.
It's worth noting that China and Russia actively assisted in jamming Starlink in Iran".
