The Launch of Ariane 6: An Overview of ISTSat’s Aircraft Spotting

Europe’s newest rocket, the Ariane 6, is ready to embark on its first flight, carrying numerous space missions with diverse objectives, destinations, and teams. This heavy-lift launcher will showcase its versatility and flexibility as it launches new satellites for various purposes. One such satellite is the ISTSat-1, developed by the University of Lisbon in Portugal.

ISTSat-1 is a CubeSat, a small cube measuring just 10 cm wide, that will be deployed into orbit at an altitude of 587 km above the Earth. Weighing just over 1 kg, the satellite will utilize a flat, patch antenna to receive Automatic Dependent Surveillance Broadcast (ADS-B) signals from aircraft. ADS-B is a system used by aircraft to constantly broadcast their information to air traffic control, ensuring safe and efficient transport. However, there are areas, particularly over the ocean, where this information is not received by ground receivers. By deploying ISTSat-1 into space, these blind spots can be monitored, improving the overall surveillance system.

While monitoring aviation is ISTSat-1’s primary mission, it also aims to inspire people in Portugal with its challenging space project. Students from various disciplines including aerospace engineering, electrical engineering, communication networks, and computer engineering have been working on this project, gaining valuable hands-on experience in designing, building, and managing space missions. This project is part of the European Space Agency’s (ESA) education program called “Fly Your Satellite!”, providing students with a unique opportunity to participate in their own satellite project and learn from the working methods adopted in professional space programs.

Success for ISTSat-1 is measured not only by its ability to receive and transmit accurate aircraft ADS-B data but also by its role in Europe’s rocket launch history. The data received by ISTSat-1 will be cross-checked with official aircraft ADS-B flight data at a ground station in Portugal. If the data matches, the team can proudly claim that they successfully built an operational satellite that flew on the maiden flight of the Ariane 6. This achievement would undoubtedly be an impressive addition to their resumes.

Furthermore, this mission will provide valuable insights into the characteristics of the school-developed antenna. The team will determine its range, angles at which it can pick up signals, accuracy, and robustness. Letícia Araújo, a member of the ISTSat-1 team, expresses her excitement about making history as the first Portuguese university satellite launched on Europe’s heaviest rocket. The experience and challenges faced during the design and build process have equipped the team with valuable skills and expertise. The hope is that the success of ISTSat-1 will inspire future generations in Portugal to pursue their own space projects.

The launch of the Ariane 6 carrying ISTSat-1 and other missions signifies Europe’s continuous progress in space exploration and technology development. It highlights the collaboration between academia and industry and serves as a platform for educational programs like ESA’s “Fly Your Satellite!” initiative. As more universities and students actively participate in satellite projects, the scientific community benefits from their innovative ideas and contributions.

In conclusion, Europe’s new rocket, Ariane 6, is set to launch with a payload of exciting space missions. Among them, ISTSat-1, a CubeSat developed by the University of Lisbon in Portugal, aims to monitor aviation using its ADS-B signal reception capabilities. This project not only provides unique educational opportunities for students but also contributes to Europe’s rocket launch history. The successful deployment and operation of ISTSat-1 will be an inspiration for future generations of space enthusiasts in Portugal and beyond.
