KSAT operates two polar ground stations optimized for low Earth orbit (LEO) satellites, the other being TrollSat at Troll in Antarctica. [22] These are the only two ground stations able to see a polar-orbiting satellite on every revolution. [24] By using both stations, customers can communicate with a satellite twice per orbit. [10]
