Satellite Data in Agricultural and Environmental Economics: Theory and Practice

open access: yesAgricultural Economics, Volume 56, Issue 3, Page 493-511, May 2025.
ABSTRACT Agricultural and environmental economists are in the fortunate position that a lot of what is happening on the ground is observable from space. Most agricultural production happens in the open and one can see from space when and where innovations are adopted, crop yields change, or forests are converted to pastures, to name just a few examples.

Thermal modelling of the PICSAT nanosatellite platform and synergetic prestudies of the CIRCUS nanosatellite

open access: yes, 2016
In the present paper, which was written in collaboration with the Observatory of Paris, thermal models of two CubeSat missions were created. The first goal of this work was to create a nodal simulation of the PicSat satellite to verify the survivability of the system within the extreme space environment.

Nanosatellites and Applications to Commercial and Scientific Missions

open access: yes, 2020
In the past two decades, a silent revolution has taken place in the space domain, leading to what today is known as “New Space.” We have passed from a selected group of countries, space agencies, and big industries building, launching, and operating satellites and other spacecrafts, of a scenario in which many universities and research institutes can ...
