The global Weather Forecasting Services Market was valued at US$ 3.6 billion in 2022
The Satellite Orbit DecAy (SODA) service, created in collaboration between the University of Graz and TU Graz, completed a successful test phase and was formally integrated into the ESA's Space Safety Programme.?
SODA offers accurate prediction of the impact of solar storms on satellites in low Earth orbit. TU Graz is now only the third Austrian institution involved in this ESA program. The Kanzelh?he Observatory and the Institute of Physics at the University of Graz, along with Seibersdorf Laboratories, have formerly contributed to the work of the organization. Thus, these types of steps by the company create a positive influence on the global #weather #forecasting #services #market. In addition, according to a research report published by Astute Analytica , the Global Weather Forecasting Services Market is estimated to increase at a #cagr of 12.6% during the forecast period from 2023 to 2031.?
The new forecast service provides a free warning with a lead time of roughly 15 hours and is accessible through the ESA Space Weather Service. The commissioning of SODA is of special relevance at this point since solar activity is anticipated to peak during the next two years. The SWEETS experiment, supported by the Austrian Research Promotion Agency (FFG), whose findings SODA is based, showed how much solar storms can impact satellite trajectories. Air density data was merged with in-the-moment measurements of the solar wind plasma and the interplanetary magnetic field to determine the consequences of solar events. This study has demonstrated that for satellites at an altitude of 490 kilometers, significant coronal mass ejections can cause orbital decays of up to 40 meters. A solar storm caused the loss of 38 Starlink satellites just minutes after they were launched at a height of 210 kilometers.?
The greatest level of solar activity?
The main reason for such altitude losses is that the charged plasma particles that the Sun emits collide with the Earth's magnetic field, heating and expanding the higher layers of the atmosphere. As a result, the air drags increase, which lowers the speed and altitude of satellites. The ESA has already raised several of its satellites' heights by a few kilometers in preparation for the impending solar maximum to survive this time safely. The predictions made by SODA are therefore meant to provide an additional layer of protection. TU Graz provided its expertise in the processing of satellite data made accessible at the Institute of Geodesy, while the University of Graz's participation was based on its competence in the field of heliospheric physics and solar as well as interplanetary magnetic field monitoring.?
The team from the Institute of Geodesy at TU Graz, directed by Sandro Krauss, examined air concentrations for 20 years. They used data from the GRACE, CHAMP, GRACE Follow-on, and Swarm missions, among others, to do this. Around 300 solar storms recorded between 2002 and 2017 were examined by a team at the University of Graz under the direction of Manuela Temmer from the Institute of Physics using data from probes at the L1 Lagrange point, 1.5 million kilometers away from Earth and facing the Sun. This point is where measurements of the interplanetary magnetic field were taken. TU Graz then used the data to link the fluctuations in air density to these solar storms. The combined examination of these multidisciplinary datasets led to the development of the forecasting model SODA.?
Austria values space exploration highly?
Sandro Krauss from the Institute of Geodesy at TU Graz expresses his happiness that, “TU Graz, alongside Seibersdorf Laboratories and Uni Graz, is now the third Austrian university to contribute to the ESA's Space Safety Programme through SODA. "Of the five Expert Service Centres that make up the ESA Space Weather Service Network, only the United Kingdom is currently active in all five. Austria is now represented in four of the five. This demonstrates quite clearly how highly esteemed space research is in Austria. Another illustration of the value of multidisciplinary research is the collaboration on this project with the University of Graz. And firms are already collaborating to make SODA even better.”?

The University of Graz's Institute of Physics' Manuela Temmer stated, "For TU Graz and Uni Graz, providing this service to ESA is a welcome validation of our efforts. I am also happy that our collaboration will continue as the firm seek to enhance SODA as a team as part of the CASPER project, which is sponsored by the FFG. Firms will be better able to comprehend more intricate solar storms, such as those that collide as they approach Earth. The lowest height at which we can now calculate air density is 490 kilometers, but we would also like to calculate it at 450 and 400 kilometers. Firm anticipate some fascinating results because the topic of solar storm forecasting has not yet been well studied.”?
