Hartebeesthoek Radio Astronomy Observatory

Hartebeesthoek Radio Astronomy Observatory (HartRAO) is SARAO’s active radio astronomy and space-geodesy site about 65 kilometres northwest of Johannesburg, operating 26-metre and 15-metre telescopes, GNSS and geodetic equipment, satellite laser ranging, and a VGOS station under commissioning. SARAO’s current public-open-day page documents access through announced, capacity-limited open days with mandatory registration and signed indemnity forms; check SARAO before travel because the operational site is not a routine walk-in destination.
