Ground System
A ground system is the entire network of facilities, hardware, and software on Earth used to communicate with, track, and control spacecraft. It's the Earth-based part of a space mission.
TECHNICAL DEFINITION
A Ground System (GS) is the integrated terrestrial infrastructure, including ground stations, mission control centers, data processing facilities, and communication networks, designed to support space mission operations, telemetry reception, command transmission, and data archiving.
BACKGROUND
The Korean Positioning System is a regional satellite navigation system currently under development by the South Korean government. It will consist of a total of eight satellites, the first of which is scheduled to be launched in 2027. Full operational capability is expected in 2035. KPS will provide an independent positioning, navigation, and timing (PNT) service in the Asia-Oceania region and can also be compatible with other global navigation satellite systems (GNSS).
