You appear to have received some misinformation above. All 3 devices
will share the bandwidth from the satellite link. Functionally, in this
situation there is no difference between a switch and a hub. They both
connect multiple devices. A so called "router" allows one IP address to
be assigned by the ISP and used by all computers. Neither a switch nor
hub will do that. If you have only one IP address, a switch or hub will
not suffice. A router uses port and address translation, to make all
computers appear as one, to the ISP, so that a single IP address can be
shared by multiple computers.
