VSAT coverage refers to the geographical areas where a satellite internet provider offers service. Marine VSAT systems rely on global or regional beams provided by satellites in geostationary orbits. Ku-band and Ka-band services offer wide coverage across oceans, shipping routes, and remote regions. Coverage maps vary by provider—vessels must select systems that cover their navigation zones. Seamless coverage ensures uninterrupted communication and is vital for safety, compliance, and digital operations on open waters.
