Geodesists on Tour: GPS measurements on Antarctica

Geodesists on Tour: GPS measurements on Antarctica

  Stories from the field – how exactly are those GPS data collected? The geodesy community at large benefits from the many science projects with open data policies.  A user simply has to navigate to a data portal, download the data, and within a matter of moments a world of possibilities opens up for potential research.  But where exactly do these data come from?  While scientific results get ...[Read More]

Geodesists on Tour: Gravity measurements on Antarctica

Geodesists on Tour: Gravity measurements on Antarctica

  Antarctica is well known for its large ice sheet, covering 98% of the continent. A large part of the ice sheet is losing mass leading to vertical and horizontal movements of the crust as well as changes of the gravitational attraction. To observe these changes in gravity with the highest accuracy, it is necessary to visit Antarctica and measure gravity on a regular basis. Since the late 198 ...[Read More]

Starting a PhD during a pandemic

Starting a PhD during a pandemic

  Have you ever wondered what it means to start a PhD during the pandemic? Below you can get more insights.   Hi! I’m Öykü, a PhD student at Politecnico di Milano in Italy. I’m originally from Turkey and did my MSc at Istanbul Technical University. My research focus is static and time-variable gravity field recovery from satellite data and local gravity field modelling. Currently, ...[Read More]

Gravity time series still reveal new insights

Gravity time series still reveal new insights

          View of the Medicina observatory. The site hosts a superconducting gravimeter (SG) installed in a dedicated building next to a piezometer. Local height variations  are monitored by means of two GPS stations, located at the end of the N-S segment of the “North Cross” radio telescope. The two GPS stations are about 30 m apart and are close to a VLBI antenna.   ...[Read More]
