Graduation Project: Thesina

Ground Station for Satellites

For my graduation project as an electronics engineer, I had the opportunity to develop a ground station, a crucial component for communication with satellites and other space platforms. This project was an exciting challenge that combined my technical knowledge, my passion for engineering, and my interest in space exploration. Below, I will share the key aspects of this project, from its conception to its implementation.

What is a Ground Station?

A ground station is a telecommunications system that enables the reception and transmission of data between Earth and orbiting satellites. These stations play a vital role in applications such as Earth observation, meteorology, telecommunications, and space research. My project focused on designing a low-cost, high-functionality version that could be used in educational and research applications.

Project Objectives

Design and Construction: Create a modular and scalable system that could be assembled using accessible components.
Technology Integration: Incorporate software and hardware technologies to optimize data reception.
Educational Application: Develop a system that could be replicated by students and engineering enthusiasts.

Project Phases

Initial Research: During this phase, I researched the technical specifications of existing ground stations, identifying key components such as antennas, transceivers, and tracking software. I ensured that the chosen technologies aligned with my budget and objectives.
System Design: I used tools like LabVIEW to develop the control and monitoring software for the station. This graphical development environment facilitated the integration of sensors and actuators, enabling precise antenna control and data reception.
Construction and Assembly: I designed a mechanical structure to support the antenna and ensure its precise orientation toward target satellites. Additionally, I integrated a stepper motor system for motion control.
Testing and Validation: I conducted extensive testing to ensure the system’s functionality. This included receiving signals from weather satellites and decoding the data.

Challenges Faced

Budget Constraints: I opted for low-cost components without compromising the system’s quality, which required thorough research.
Tracking Precision: Adjusting the motors to achieve precise orientation was a challenge that I overcame through iterative adjustments and optimized code.
Software Integration: Ensuring compatibility between the control software and hardware components was critical to the project’s success.

Impact and Future

This project not only allowed me to apply my knowledge in electronics engineering but also contributed to my goal of promoting STEM among young people, especially girls and women. I plan to share the design and results with the community, fostering interest in space exploration and engineering.

Conclusion

Developing this ground station was a transformative experience that solidified my passion for engineering and space exploration. I hope this blog inspires others to pursue their own projects and explore the infinite possibilities of science and technology.
