It is already mentioned that ISS orbit the earth 15 times a day, how we design a dish network to stay communicate with it along its path? Are we build a dish in Atlantic Ocean too?
NASA communicates with the ISS through their Space Network, which consists of a constellation of satellites including ones in geosynchronous orbit, low earth satellites, and ground facilities that relay between NASA and the satellites. It's available 24/7 and allows constant communication with the ISS, including voice, telemetry, etc.
While the Apollo-era space program had to rely on ground stations for communication, a network of geostationary satellites called TDRSS has been in use since the 1980s to provide continuous communication with spacecraft in orbit (as well as to the south pole!).
