Space Operations

Products & Services

The SANSA Space Operations Programme specialises in a wide range of space mission support services. With over 60 years in operations the Hartebeeshoek facility has become one of the most sort after ground stations in the world. SANSA Space Operations operates and maintains more than 40 locally installed antennas and many ground stations on site.

The facility provides full-motion TT&C (telemetry, tracking, and command) antennas, and remote sensing systems across all frequency bands (and in S-band for mobile support).

The activities of the TT&C group at SANSA Space Operations are driven primarily by the needs of international clients. The operational efficiencies that these clients require have driven the consistently reliable performance of the Space Operations division at Hartebeesthoek, which has established itself as the most reputable TT&C tracking station on the African continent.
