You can trade off speed for transmission gain. Or bigger antenna on the sat ( foldable, multi-element for beam forming ).

See Huawei’s Mate 60 Pro for instance.

Also the latest Beidou satellites ( china GPS ) actually include a SMS service !

@ploum Of course you area absolutely correct that GPS receiver is ... a receiver.

But I'd still want to point out that is is absolutely possible to make pocket sized transmitters that can reach satellites.

Benefits of large antenna in space / beam forming / coding gains / ....

It wouldn't be fast or anything, but for instance, apple sms over sat, or distress beacons, ...

I know, it's long overdue ... sorry about that 😅
