Satellite connection on your phone is about to make a big splash globally. Massive players like Apple, SpaceX, T-Mobile and Qualcomm are investing billions in this vision of planet wide, always on connection. How could small satellites, and specifically, CubeSats use this tech to make their missions easier and safer? That's what we are talking about in this side note.

*Summary*
- Direct to Cell technology (#dtc , also called mobile satellite services, MSS) allows regular phones to work via satellites.
- There is massive investment in DTC technology worldwide with a number of companies starting to bring satellites online - #AST and #lynk are two of those.
- #spacex is starting to roll out text messaging through #starlink in 2024 in some countries via partnerships with local network carriers, like T-Mobile in the US.
- Calls and data connections are to follow in 2025.
- Deployment of larger Starlink V2 satellites is a driver for the #starship program's pace.
- All in all, DTC is here to stay.
- Potentially, this technology can be used in the future to make data connectivity for small satellites like #cubesat and PocketQubes significantly easier and more affordable.
- It remains to be seen if this is a viable approach, as doppler shift and timing will be different for LTE modem on the ground vs. in LEO.
