 Additionally, 12 photodiodes ([Vishay, Cat. No. TEMD6010FX01](https://www.vishay.com/en/product/81308/)) were implemented as Sun sensors, two on each face of the satellite (for redundancy). The selected photodiodes were digitized via a voltage divider and an Analog-to-Digital Converter (ADC) ([Texas Instruments, Cat. No. ADC128D818](https://www.ti.com/product/ADC128D818)). All sensors were sampled and controlled by a microcontroller ([Microchip, Cat. No. ATMEGA328P](https://www.microchip.com/en-us/product/ATmega328P)) on the ADCS PCB [[1]](#user-content-references).

 Quetzal-1 was a 1U CubeSat developed by an engineering team from [Universidad del Valle de Guatemala](https://www.uvg.edu.gt/) (UVG). The satellite was deployed from the International Space Station's (ISS) KiboCUBE module, on April 28, 2020, and operated succesfully in space from the day of deployment to November of the same year. This amounted to 211 days of operation, which validated the performance of all systems on-board.

 General information on the project is available on [the official site](https://www.uvg.edu.gt/cubesat/), including news and scientific publications that have been released throughout the project's lifetime. You can also check out [this live session on Arduino's EDUvision](https://www.youtube.com/watch?v=YOHguG6epe4&t=1319s&ab_channel=Arduino), where one of our team members speaks about the story behind Quetzal-1, from its inception to the time our satellite spent in space!
