We would like to thank the Slovak Space Office for organizing this incredible opportunity to promote education in the field of space science.

At Needronix, we are committed to supporting education in Slovakia and attracting talents into the space industry, especially through activities like CanSat.

The CanSats in Europe initiative, led by the European Space Agency (ESA), works in collaboration with local organizations to enhance support for CanSat activities across the continent. A CanSat is a simulation of a real satellite designed to fit within the dimensions of a soft drink can. The challenge for students is to incorporate all essential satellite subsystems—such as power, sensors, and communication—into this compact space. Once assembled, the CanSat is launched to an altitude of a few hundred meters, either by rocket, dropped from a balloon or in Slovakia’s case dropped from a drone (UAV). The mission then begins: to conduct a scientific experiment and ensure a safe landing.

The 1U CubeSat GRBAlpha, on which we collaborated, **made history by capturing the massive gamma-ray burst GRB221009A** and providing insights into its characteristics.

The idea of using CubeSats for the purpose of studying gamma-ray bursts was developed by Norbert Werner, an astrophysicist, in collaboration with astronomer András Pál.

Norbert Werner approached two Slovak aerospace companies, Needronix and Spacemanic, to build a nanosatellite for their gamma detector.

**Needronix was a key developer, designer and integrator of the GRBAlpha satellite**. We also developed the NXTRX4 Cormorant transceiver and the NXSS3 Eagle fine sun sensors for this mission. We also handled all communications with the GRBAlpha satellite for the first month after launch, using our own ground station.
