- Abstract:
In today's dynamic space exploration landscape, the need for cutting-edge technologies has
never been more crucial, especially in optimizing Earth observation missions. This investigation
aims to provide an accurate characterization of the 3Cat-Gea camera, installed on the 3Cat-8
Satellite of the UPC NanoSat Lab. With a linear polarizer, this camera has been selected for
studying aurora borealis emission and its effects on ionospheric radio propagation. This work is
focused primarily on understanding the complexities of this camera, and performing a full characterization and calibration of the system.
- Objectives:
The main goal is to efficiently characterize the camera, evaluate the complete sensor, lens
and filter assembly spectral and optical performance. We'll also focus on implementing
polarizer control and integrating software *to calibrate the images and ensure their proper
quality during Aurora borealis observances. Additionally, we aim to develop programs for
capturing high-resolution images and enabling rotor rotation, ultimately integrating all
components into a cohesive system and conducting comprehensive testing to ensure functionality in space environments.*
- *Method:
The methodology involves conducting a comprehensive characterization of the camera's
parameters, implementing polarizer control for enhanced image quality during aurora borealis
observations, integrating necessary software* for efficient operation, and developing specific
programs for image capture and rotor control.
Expected results:
The expected results of this study include a comprehensive understanding of the performance
and capabilities of the 3Cat-Gea camera on the 3Cat-8 satellite and achieve the necessary
image quality during captures by proper calibration. Additionally, a first high-level integration
of software *for efficient data processing, and the successful development of programs for
image capture and rotor control will be used for the image captures.
 
Overview (resum en anglès):
The main objective of this thesis is the understanding and characterization of the SUSIE hyperspectral camera, designed to capture the spectra of the northern lights. It will be integrated in the 3Cat-8 mission satellite, which aims to study atmospheric phenomena such as ionospheric scintillation.

This project covers both the assembly of the hardware (including the integration of the sensor, rotor, lens and polarizing filter) and the verification of the camera performance through different experimental tests in the Clean room. Different methods and techniques will be used for spectral characterization, such as the study of the linearity of brightness, dark current and defective pixels.

The last two chapters will deal with the study of the modulation transfer function and its possible effects on the mission, together with the testing of the communication system between the camera and the C3SatP, which will ensure that the data collected are managed correctly.

Ultimately, the goal is to verify the operability of the camera in the space environment, as well as the contribution in observation techniques for future missions.
