Terma Celebrates 25 Years of the Ørsted Satellite

The Ørsted satellite was launched in 1999 as a groundbreaking project aimed at advancing scientific research and exploration in space. Named after the renowned Danish physicist Hans Christian Ørsted, the satellite was equipped with cutting-edge instruments designed to study Earth's magnetic field and its interaction with solar wind. This initiative marked a significant milestone for Denmark in space exploration, solidifying its presence in the global space arena.

Since, the Ørsted satellite has surpassed all expectations, celebrating an impressive 25 years in orbit when initially planned for a 14-month mission. Over the years, it has delivered valuable data and insights into the Earth's magnetic field, contributing to scientific advancements, including the precise mapping of the Earth’s internal field, and expanding our understanding of space. This has positioned the Ørsted satellite as a symbol of Danish space success, receiving recognition for its longevity and the wealth of scientific data it has provided.

Terma is honored to have played a crucial role in the Ørsted satellite's success through the provision of robust and reliable space equipment. Terma’s space equipment including critical components such as the Power Control Units, On-Board Computers and On-Board Software, have demonstrated exceptional durability in the challenging conditions of outer space.

The Ørsted satellite stands as a living testament to the durability and reliability of Terma’s space equipment. Rigorously tested to withstand extreme conditions, Terma's contributions have ensured that the Ørsted mission has not only met but exceeded its intended operational life.

Flemming Hansen, closely involved in the Ørsted project since its initiation in 1992, emphasizes the significant influence of the Ørsted satellite on the Danish space industry and the study of Earth's magnetic field: “The Ørsted satellite has provided a tremendous yield, both for the intended research and for the participating companies and research institutions. In the years following its launch, Danish researchers secured a leading position in the study of Earth's magnetic field, a position that is still maintained. Additionally, the Ørsted satellite has served as a pioneer for many space products at Terma, further research in Earth's magnetic field, such as the ESA-led SWARM mission, and as a contributor to the development of several Danish satellites and the establishment of new Danish space companies. Even though it is now considered old in a space setting, it still functions and continues to transmit data.” says Flemming Hansen, former Chief Adviser, DTU Space, National Space Institute and Senior Systems Engineer, Alcatel Space Denmark.

As we celebrate the Ørsted satellite's 25th anniversary, we look to the future with optimism and determination. This milestone sets the stage for future endeavors, underlining Terma's commitment to pushing the boundaries of space exploration. The success of the Ørsted project serves as an inspiration for ongoing and future missions, reinforcing our dedication to excellence and the pursuit of scientific knowledge.

Terma remains at the forefront of innovation, contributing to the success of space missions that shape our understanding of the universe. With over 50 years of expertise in the space industry, Terma has established itself as a trusted partner in space exploration. Building on its extensive experience, Terma continues to pioneer new projects that push the boundaries of space exploration. Among its newer initiatives, Terma's participation in the second part of the ExoMars mission highlights its commitment to advancing our knowledge of the Mars. This endeavor underscores Terma's dedication to pushing the limits of what is possible in space exploration and solidifies its position as a leader in the field. The Ørsted satellite's longevity and enduring legacy is a testament to the collaborative spirit of Danish space exploration and the reliability of Terma's space technologies.
