Purpose

The original function of the observatory post-NASA was purely research in radio astronomy, but a new science developed at the SARAO Hartebeesthoek site from the 1980's, namely Space Geodesy, i.e. geodesy using space techniques. The Hartebeesthoek Radio Astronomy Observatory (HartRAO), located near Johannesburg, South Africa, is a premier facility dedicated to radio astronomy research and space geodesy. Its primary purpose is to observe and study celestial phenomena by detecting radio waves emitted by astronomical objects such as galaxies, quasars, pulsars, and molecular clouds. Equipped with advanced radio telescopes, HartRAO contributes to our understanding of the universe by investigating the structure, dynamics, and evolution of cosmic entities. The observatory also plays a significant role in international collaborations, participating in global research initiatives and sharing data with the broader scientific community to advance the field of radio astronomy. In addition to its astronomical research, HartRAO is actively involved in space geodesy, using radio telescopes to conduct precise measurements of the Earth's shape, rotation, and gravitational field. These measurements are critical for applications in navigation, climate monitoring, and understanding tectonic movements. The observatory's contributions to space geodesy enhance our ability to monitor and predict changes in the Earth's environment, supporting both scientific research and practical applications. Through its dual focus on radio astronomy and space geodesy, HartRAO serves as a vital center for scientific exploration and technological development, furthering our knowledge of both the cosmos and our own planet.
