Ground infrastructure in cybersecurity refers to the network of earth-based stations and facilities that support communication with satellites. This infrastructure includes antennas, control centers, data routing systems, and supporting hardware that enable the transmission, reception, and management of data between satellites and terrestrial networks. Ground infrastructure is critical for ensuring secure, reliable, and continuous data flow in satellite communications, supporting services such as GPS, internet, and remote sensing. Protecting ground infrastructure from cyber threats is essential, as attacks can disrupt communications, compromise sensitive data, or even take control of satellite assets.
