Research

I am an External Collaborator of the Celestial Mechanics Group at the Department of Mathematics (University of Pisa).

My research is about Orbit Determination and Radio Science experiments of space missions.

I am a ORBIT14 software developer.

Orbit determination and Radio Science

Determination of the gravity field of planets via interplanetary orbiter.

Ring mascons model for the gravitational potential of fluid planets.

Study of the rank deficiencies in the orbit determination problem.

Radio Science for the Juno mission to Jupiter.

Chaotic orbit determination.

Lense-Thirring effect determination in the Solar System.

ORBIT14

ORBIT14 is an orbit determination and parameter estimation software developed by the Department of Mathematics (UniPi) and Space Dynamics Services srl.

It is a mission-specific software, able to process Doppler and ranging data of the ESA's BepiColombo and the NASA's Juno mission.

Part of my PhD job was to develop the differential corrector part of the software for the Juno mission.

PhD Thesis

My research project during graduate school was to perform numerical simulations of the NASA's Juno mission Radio Science Experiment with the ORBIT14 orbit determination software. Simulations included Jupiter's Gravity Field determination, Rotation axis and Angular Momentum from the Lense-Thirring effect. You can find my dissertation below.

Master Thesis

I first approached Orbit Determination for my Master Thesis. In that occasion we developed a semi-analytic theory for estimating the uncertainty in the determination of the gravity field of a planet via interplanetary orbiter. We applied the method to the Juno mission. You can find my dissertation below.
