| This project aims to carry out nanosatellite Standalone Subsystem
Verification (SSV) in ambient conditions and subsystem Environmental Test Campaign (ETC) at NanoSat Lab. The subsystems subjected to testing will be a Commercial-Off-The-Shelf (COTS) hyperspectral camera for Earth Observation belonging to the RITA Payload and the Nadir Antenna Deployment Subsystem (NADS) belonging to the 3Cat-4 CubeSat. The work will conclude with the integration of the 3Cat-4 CubeSat. The different tasks and workplan of the project entails: - Hyperspectral camera blur analysis under thermal transitions using a Thermal Vacuum Chamber. - Hyperspectral camera blur analysis under launch conditions using an electrodynamic shake table. - Calibration of the hyperspectral camera. - Camera data transfer testing between the payload interfaces. - Application of image compression algorithms and software development for imaging data management. - Thermal testing of the NADS subsystem using a Thermal Vacuum Chamber (TVAC). - Vibrations testing of the NADS subsystem using an electrodynamic shake table. - Integration of the 3Cat-4 nanosatellite. - Writing of a thesis and preparation of a presentation |

| Overview (resum en anglès): | |
| In the context of the booming new space market and the empowerment of the Earth Observation field through the incorporation of affordable technologies with acceptable performance, this thesis brings together a series of activities carried out in the Phase D of the 'Remote sensing and Interference detector with radiomeTry and vegetation Analysis' RITA mission, being focused on the characterisation, understanding and verification of a low-cost Commercial Off-The-Shelf hyperspectral camera.
First and foremost, the subsystem is evaluated and a survey is carried out to devise a simplified mathematical model that defines the experimental measurement to be carried out through the relevant parameters involving the image acquisition. These identified performance indicators (such as the dark current generated at the sensor, the vignetting effect of the lenses or the quantum efficiency) guide the definition of a test plan, as they will significantly affect the quality of the measurements in orbit. Once the tests are defined, they are carried out thanks to the availability of equipment used in the space industry, such as a thermal vacuum chamber or a monochromator. The verification campaign of the camera, distributed in three global phases: verification of the optical-electrical response, verification of the response under environmental conditions and characterisation of the spectral response, leads to satisfactory results. Finally, the subsystem is integrated at a logical and physical level with the rest of the elements that make up the payload. In the first case, a successful communication test is established between the camera and the Interface Board and a preliminary version of the program in charge of executing the camera experiment is developed. In the second, the camera presents a correct mechanical fit with the rest of the payload components. The project encompasses a series of activities executed through standardised procedures that allow the correct verification and integration of a subsystem so that it can form part of the composition of a satellite. These conclude with the camera being ready for launch into orbit, in the expectation of confirming that the vibration test results do not expose any critical limitations. |
