European Space Agency’s Harmony mission to rely on ABB infrared instruments

• ABB to develop thermal infrared (TIR) imaging instruments for two European Space Agency Harmony satellites, helping the research mission gather new data on Earth’s dynamic systems

• ABB technologies will contribute to the advancement of climate science and the understanding and forecasting of extreme weather events

• Combining thermal and radar imagery enables deeper insights into energy fluxes and exchange processes occurring at the ocean-atmosphere interface

ABB has been selected by the German space and technology company OHB System AG to develop and build the thermal infrared payloads for the European Space Agency’s (ESA) Earth Explorer Harmony satellites, planned to launch in 2029. ABB will equip the two satellites with multispectral thermal infrared payloads capable of measuring a wide range of environmental parameters, including sea surface temperature and the position of clouds and their motion. Financial details were not disclosed.

ABB’s multiview TIR instrument will enable ESA to measure cloud position and motion from space, ensuring radiometric precision – the accuracy of the temperature measurement obtained by the infrared instruments compared to that of the true surface temperature (whether cloud or sea). The data collected by the mission will help the advancement of climate science as well as support the understanding and forecasting of extreme weather such as hurricanes. In addition, over land, Harmony will provide information to estimate small shifts in the shape of the land surface, such as those leading to and resulting from earthquakes and volcanic activity, thereby contributing to the assessment of geohazards over geologically active areas.

“Harmony is poised to further enhance our understanding of how our planet works by delivering valuable data that will benefit Earth system science and climate research,” said Florence Hélière, Harmony Project Manager, European Space Agency. “The expertise and commitment of our industrial partners are invaluable for the Harmony mission, helping us to deliver the mission on time and advance scientific knowledge.”

“We selected ABB on this high-profile mission because of their proven expertise in infrared sensor technologies,” said Agustina Alvarez Toledo, Harmony Project Manager at OHB System AG. “We have been collaborating on several space programs and know that they are very capable. We look forward to working together again to support the scientific community for the benefit of this generation and the ones to follow.”

“ABB's purpose is to enable a more sustainable and resource efficient future and so we are proud to be a part of this scientific program that will contribute to humanity’s understanding of climate change,” said Jacques Mulbert, President of ABB Measurement & Analytics. “With this work, we are showcasing our ability to provide accurate cloud positioning and sea surface measurement from space, contributing to a deeper scientific understanding of our planet in order to preserve its future.”
