Geodetic Surveys of the Grove Mountains: History and Future Work

This paper presents the findings and developments from geodetic surveys conducted in the Grove Mountains region, showcasing a historical perspective from the 1958 astro fix near Mt. Harding to recent GPS observations in 2000-2001. Key highlights include the collaboration between Australian, Russian, and Chinese exploration efforts, including airborne geophysical studies and ground expeditions. Future work aims to enhance geodetic infrastructure, support uplift studies, and establish connections between different geodetic datums, facilitating better global positioning and research in Antarctica.
