Copernicus is the Earth observation component of the European Union’s Space programme. It provides accurate, timely and easily accessible information to improve the management of the environment, understand the effects of climate change and ensure civil security. Copernicus provides a unified system through which vast amounts of data from upwards of 30 satellites are fed into a range of thematic information services designed to benefit the environment, the way we live, humanitarian needs and support effective policy-making for a more sustainable future. This plenary speech will highlight current and future power technologies enabling Copernicus. Power electronics are essential for satellite energy management, battery health, and reliable power distribution. As avionics advance, they require lower voltages and higher currents, while scientific instruments need specialized supplies. The rise of large satellite constellations demands innovative solutions to cut costs and speed up delivery without sacrificing reliability. GaN switches and digital control are transforming space power electronics, enabling more efficient, robust systems for next-generation satellites.
