As a core member of the UIU CanSat Team, I contributed to the design and development of a miniaturized satellite system capable of collecting and transmitting atmospheric data during descent. The CanSat was engineered to simulate the key functions of a real satellite, including data acquisition, telemetry, and recovery, within a compact, cost-effective structure. My primary contributions were in the software, communication, and electrical segments. I developed the embedded software responsible for sensor data acquisition, telemetry encoding, and in-flight control logic. I also designed and implemented the wireless communication system between the CanSat and the ground station, ensuring stable and real-time data transmission. Additionally, I worked on the electrical integration, optimizing power distribution and circuit reliability under high-vibration and temperature conditions. Through this project, I deepened my expertise in embedded systems, IoT communication, and satellite telemetry, contributing to the successful flight and data recovery of the UIU CanSat mission.
