Could you build this?
No Exosat designs, builds, and operates low Earth orbit communication satellites for direct-to-device and broadband connectivity.
What it would actually take: This demands aerospace hardware engineering, RF/antenna design for Ka-band and 3GPP non-terrestrial networks (NTN), orbital mechanics, radiation-hardened electronics, thermal vacuum testing, and securing international spectrum licenses (ITU/FCC). It also entails launch vehicle contracts and building distributed terrestrial ground gateway stations. The work strictly requires veteran aerospace engineers, RF telecom scientists, and tens of millions in capital.

Same idea, different domain
Nobody's really built a hardware & robotics tool for Horizontal yet.
