![]() ![]() Hinode Satellite Captures X-ray Footage of Solar EclipseĬontributing to next-generation missions to study the Sun. The XRT observes X-rays from the solar wind and CMEs. Researchers at the Smithsonian helped design and build the X-ray Telescope (XRT) for the Japanese Space Agency’s Hinode spacecraft. Using space-based X-ray telescopes to monitor the Sun’s weather. These carry instruments high enough to allow researchers to observe the high-energy radiation driven by the Sun’s magnetic field. Much of the radiation from the corona is blocked by Earth’s atmosphere, requiring the use of stratospheric rockets such as the Hi-C mission. Studying the Sun’s corona using instruments on high-altitude rockets. In order to comply with the stringent operational service requirements, a dedicated facility for monitoring is available to the forecasters to review the advisories before issuance.Center for Astrophysics | Harvard & Smithsonian researchers study space weather in various ways: The ESSP space weather team developed a set of software tools, operational procedures and an organizational system to achieve the most efficient monitoring service. These missions are performed using various sensor data that feeds forecasting models to elaborate alert advisories which are broadcasted to the main aviation actors. ![]() Oversighed by the DGAC and supported by the French scientific community, ESSP, CLS and Météo-France form the SPECTRA consortium providing GNSS and Radiation service in the ACFJ consortium. These global centers broadcast alert advisories to the aviation to warn about solar and geomagnetic storms that not only can cause disruptions to the communication and positioning systems but also expose aircraft crews and passengers to high levels of radiation.Įach global Space Weather monitoring center is in charge of delivering a continuous Space Weather monitoring service by publishing daily briefs describing the space weather situation and by publishing advisories in case of events that could impact the aviation. Recently a fourth global center joined the service: the China/Russian Federation Consortium. PECASUS : an international consortium formed by Finland, Belgium, The United Kingdom, Deutschland, Austria, the Netherlands, Cyprus, Italy and Poland.The Space Weather Prediction Center (SWPC) representing the USA.The ACFJ : an international consortium that groups Australia, Canada, France and Japan.In 2018, the following three main global centers have been selected: In 2017, The International Civil Aviation Organization launched real-time worldwide space weather service for aviation. The ICAO initiative: Global Space Weather centers designated Consequently, it becomes of interest to detect or forecast space weather perturbations and inform the international air navigation of any major space weather event potential impact. In some use cases, those perturbations can impact satellite based navigation performance. ![]() Global Navigation Satellite Systems (GNSS), relying mainly on Radiofrequency waves, are subject to perturbations and outages in case of solar events. ![]() The emitted energy and particles can travel through interplanetary space to the Earth and can affect its environment. The sun is subject to complex processes that can cause intense energy releases. Impact of Space Weather on human condition and activity Space Weather is defined by the European Space Agency as the environmental conditions in Earth’s magnetosphere, ionosphere and thermosphere due to the Sun and the solar wind that can influence the functioning and reliability of spaceborne and ground-based systems and services or endanger property or human health. The company is now involved in an international Space Weather monitoring service for aviation. Having a solid expertise in operations, service delivery and engineering and strong of its experience with Global Navigation Satellite Systems (GNSS), ESSP took the opportunity to bring its operational and technical know-how to a new field of application: Space Weather monitoring for GNSS. In accordance to its corporate strategy, ESSP is continuously seeking diverse cooperation opportunities with high added value. ESSP is involved in the provision of the ICAO space weather service to international air navigation ![]()
