Description

The 3Cat-4 is the fourth member of the CubeSat series of UPC’s NanoSat Lab, selected in ESA Academy’s Flight Your Satellite program in 2017. This mission mission aims at demonstrating the capabilities of nanosatellites, and in particular those based in the 1-Unit CubeSat standard, for challenging Earth Observation (EO) using Global Navigation Satellite System - Reflectometry (GNSS-R) and L - band microwave radiometry, as well as for Automatic Identification Services (AIS). The following study presents the results of the thermal analysis carried out for this mission, evaluating different scenarios, including the most critical cases at both high and low temperatures. The results consider different albedos and orbital parameters with the objective of establishing optimal temperatures to achieve better mission performance within the nominal temperatures and in all operational modes of the satellite.
Additionally, simulation results are included that consider the thermal performance of other materials, such as Kapton, as well as the redesign of the optical properties of the satellite’s solar panels.
