"Direct to Cell works with existing LTE phones wherever you can see the sky. No changes to hardware, firmware, or special apps are required, providing seamless access to text, voice, and data." ( from https://direct.starlink.com/ https://direct.starlink.com/ )
Seems to imply it looks just like a cellular "cell" to the phone. Which would allow for some amount of snooping.
- nerpderp82 3y agoThe Starlink constellation should be able to pinpoint every handset on ground because it forms a huge phased array antenna regardless if you are a customer or not.
- gruez 3y agoEavesdropping only gets you the TMSI which tells you there's a handset, but doesn't allow track it. If you want an unique identifier (eg. IMSI) you'll have to do a MITM attack.
- tyingq 3y ago"So far the theory. If you look at the Paging Channel (PCH) of cells in real-world networks, you see a significant (10-20%) amount of paging requests that contain paging by IMSI. This seems strange on first sight, given the theory..."[1] So you can't spy on everyone, but you can spy on some subscribers whose phone is in that state.

- teeray 3y agoI think the receiver would need some knowledge of the fact that it’s a satellite. Doppler shift is a physical phenomenon that the baseband would probably have to deal with.
- pests 3y agoThe radio chipset from Qualcomm is what is enabling the satellite connectivity so I'm sure they already have it factored in.
