CubeSat Quetzal-2 Satellite
Academic project developed by students, faculty,
and researchers of UVG
Selected by the United Nations Office for Outer Space Affairs (UNOOSA) and the German space company EXOlaunch as one of the winners of the first round of the EXOpod program, which will enable its transport and deployment into space.
What is a CubeSat?
Who is involved in the project?
A CubeSat is a small satellite (nanosatellite) developed for a specific scientific or technological mission.
They follow the CubeSat standard of California Polytechnic State University (Cal Poly), which specifies a base measure of “one unit” or “1U” of 10 cm × 10 cm × 10 cm and 1.33 kilograms, in cube form.
Multiple 1U units can be “stacked” to form larger CubeSats as mission requirements dictate. QuetzalL-1 was a 1U CubeSat measuring 10 cm × 10 cm × 10 cm, and Quetzal-2 will be a 2U CubeSat measuring 10 cm × 10 cm × 20 cm.
Due to their compact size and low cost (compared to conventional satellites), they have been a key technology in democratizing access to space. Through CubeSats, space research has been opened to students, educators, researchers, and small businesses.
What is the mission of Quetzal-2?
QUETZAL-2 will test an onboard computer designed locally, capable of running an artificial intelligence model to identify clouds in satellite imagery. It will also validate a responsible deorbit subsystem and enable the transmission of real-time satellite data to educational centers across the country, promoting open access to scientific information and strengthening education in science, technology, engineering, and mathematics (STEM).
Who is involved in the project?
The QUETZAL-2 team is made up of students, faculty, and researchers from UVG, along with external advisors.
The Phase 2 team comprises more than 40 members, including students from Mechanical Engineering, Industrial Mechanics, Mechatronics, Computer Science and Information Technologies, Electronics, Industrial Engineering, Data Science and Business Administration, as well as students from Physics and International Marketing and Business Analytics.
Key information
64% of the student team is composed of women.

Why is the CubeSat Quetzal-2 project important?
This project not only represents a technological advancement in Guatemala but also an opportunity to inspire future generations of Guatemalan scientists, engineers, and dreamers. The global satellite industry generates over $400 billion annually. We hope that in the near future, some of our students will undertake entrepreneurial ventures, create new companies in our country, and that Guatemala becomes one of the countries offering services in the value chain of this industry.
EXOpod Program
The EXOpod program of the United Nations Office for Outer Space Affairs (UNOOSA) and the German space company EXOlaunch selected 4 institutions worldwide, from among 17 proposals submitted by institutions from 15 countries, to give them the opportunity to send a CubeSat to space at no cost.
In the case of UVG, as one of the selected institutions, this program will enable the transport of QUETZAL-2 to space to place it into orbit.
Phase
Phase 1
- The QUETZAL-2 project kicked off in August 2024 with a team composed of 25 students and 4 faculty/researchers from UVG.
- This phase consisted of defining the mission, organizing the working team, and initial designs.
- During this phase, the application submitted in the first round of the UNOOSA and EXOlaunch EXOpod program was written, and in 2025 it was selected as one of the global winners.

Phase 2
- Phase 2 began in March 2025, with a team of 39 students and 7 faculty/researchers from UVG.
- This phase consists of 13 student teams developing the different submodules that make up the QUETZAL-2 CubeSat.
- During this phase, work on the satellite design continued, and the first tests of its components were conducted.

Design
1. Systems Engineering
Submodule responsible for requirements definition and management, as well as risk assessment and mitigation during mission development. It is responsible for the integration of all QUETZAL-2 subsystems.
2. Machine Intelligence for Layer Observation Payload (MILO)
Submodule responsible for designing, manufacturing, and programming the onboard computer and AI model for automatic cloud detection.
3. Communications and LoRa® Payload (COMMS & LoRa®)
Submodule in charge of the QUETZAL-2 data transmission antennas and the design and assembly of ground stations.
4. Attitude Determination and Control System (ADCS)
Submodule responsible for monitoring and stabilizing QUETZAL-2’s orientation in orbit.
5. Orbital Decay System (DEORBIT)
Submodule responsible for re-entering QUETZAL-2 into the Earth’s atmosphere (and disintegrating in the process) at the end of its useful life. This aims to reduce space debris in orbit.
6. On-board Computer (OBC)
Submodule responsible for programming the main computer and managing the QUETZAL-2 data bus.
7. Power (PWR)
Submodule in charge of capturing, storing, and managing the power required for QUETZAL-2 to operate autonomously.
8. Structure (STR)
Submodule responsible for the design, manufacturing, and integration of the metallic structure along with the rest of QUETZAL-2 hardware.
9. Thermal Simulations
Submodule responsible for simulating, evaluating, and validating the robustness of QUETZAL-2 systems against the extreme temperature fluctuations present in low Earth orbi
10. Mechanical Tasks
Submodule responsible for risk studies, simulations, and manufacturing auxiliary components and systems.
11. Cybersecurity
Submodule responsible for managing communication security with QUETZAL-2 from the Ground Station.
12. Marketing and Outreach
Submodule responsible for disseminating the QUETZAL-2 project.
13. Documentation and Handling
Submodule responsible for managing documentation and content generated before, during, and after the development of QUETZAL-2.
