Is there any system that works for at least 10-20km without line of sight, supporting a video feed usable for guidance, without cell phone network coverage?

Maybe something where there are two drones, and one flies high with line of sight to both the user and the low-flying drone so that it can act as a relay like a satellite would?

Or something that uses radio frequencies that bounce over the atmosphere, and if bandwidth is not enough uses an automated pilot plus the ability to send photos every few seconds so the user can tell it in which general direction it should fly?

Or something that uses Starlink/Iridium/etc. to relay data?
