Global gravity field modeling from Satellite-to-Satellite Tracking data

Global gravity field modeling from Satellite-to-Satellite Tracking data

With the launch of the GRACE Follow-On twin satellites in 2018, the fundamentals and details of Satellite-to-Satellite Tracking (SST) measurements between low Earth orbiters find a lot of interest these days. The low-low SST technique was very successfully pioneered by the GRACE mission (2002-2017). The pair of satellites of GRACE Follow-On, a joint NASA/GFZ mission, carries two independent and co ...[Read More]

          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]

EGU General Assembly – an adventure for newbies

EGU General Assembly – an adventure for newbies

One day in January, we heard it through the grapevine that we were supposed to submit abstracts to an event called EGU. So we asked ourselves: What exactly is EGU? Our colleagues told us: ‘EGU is a huge, international conference worth going. And you will have a lot of fun.’ So we submitted our abstracts and hoped for the best. Three months later, we entered the airport with a poster box and some o ...[Read More]
