SAM Satellite

The research Nanosatellite BGUSAT, the first of Israel, was launched from India in February 2017 as a part of a collaboration between the Ben-Gurion University of the Negev and the Aerospace Industries. Nanosatellites are a relatively new category in the field of satellites and space. These tiny satellites only weigh a few kilograms. Thanks to the minimization trend of electronic components, this platform can be instilled with advanced technological abilities for a fairly low price. The satellite is tiny- only 10X30 centimeters, the size of a milk carton, and weighs only 5 kilograms. It is equipped with cameras able to identify different climatic phenomena, and with a control system that allows selection of the research and photography areas. Ground-station for reception of the images was built in the university, allowing students and researchers to receive and analyze the data.

Peru’s first Earth Observation satellite was commissioned by the Peruvian government for its national space agency, CONIDA (Comisión Nacional de Investigación y Desarrollo Aeroespacial) in 2014, and constructed in a record time of less than 24 months. PerúSAT-1 features the very-high-resolution optical New AstroSat Optical Modular Instrument (NAOMI) imager designed and developed by Airbus Defence and Space. This silicon carbide optical instrument provides panchromatic images with 70 cm spatial resolution and multispectral images in up to 2 m spatial resolution. PerúSAT-1 is based on Airbus Defence and Space’s AstroBus-S platform, and captures up to 300 images covering an area of 63, 000 km2 per day.

DSCOVR (Deep Space Climate Observatory) is an American space weather station developed in partnership with NASA, NOAA, and the U.S. Air Force, that monitors changes in the solar wind, providing space weather alerts and forecasts for geomagnetic storms that could disrupt power grids, satellites, telecommunications, aviation, and GPS. DSCOVR orbits approximately 1.5 million km from Earth in a unique location called Lagrange point 1 (L1), the neutral gravity point between the Earth and Sun.



• Plasma-Magnetometer (PlasMag): Magnetometer and plasma sensor to measure solar wind properties for forecasting geomagnetic storms. The PlasMag instrument comprises a Faraday Cup (measures solar wind) and a Fluxgate Magnetometer, as well as two space weather instruments: the Electron Spectrometer  and the Pulse Height Analyzer.

• Earth Polychromatic Imaging Camera (EPIC): Provides images ofthe sunlit... read more

NOAA OneStop was created as a pathfinder effort to provide enhanced collection and granule searching for only those datasets archived at the National Centers for Environmental Information (NCEI). The portal provides a user-orientated point of access to weather, climate, satellite, fisheries, coastal, geomagnetic, and ocean data.



EUMETSAT and the African Development Bank (AfDB) will hold a webinar on the topic of "Earth Observation in Africa: Satellite data support for weather, hydrological and climate services" on 24 September 2020.

Since 2016, the SAWIDRA project implemented by the African Development Bank has helped local communities in Africa reduce the risk from natural disasters using satellite data. In this webinar, EUMETSAT and the AfDB hear from representatives from five Regional Climate Centres in Africa about the benefits Earth observation has brought to their areas, and discuss the future prospects for monitoring the climate, agriculture and water resources in a meteorologically uncertain future.

According to the latest issue of an annual disaster statistics report, floods were the deadliest type of disasters in 2019, followed by extreme temperature, while storms affected the highest number of people. Published by the Centre for Research on the Epidemiology of Disasters (CRED), “Natural disasters 2019 - Now is the time to not give up” draws on data recorded in the Emergency Events Database (EM-DAT), which saw the addition of 396 disasters that affected a total of 95 million and caused $103 billion in economic losses around the world. 

Accounting for 40 per cent of disaster events, Asia suffered the highest impact with 45 per cent of deaths and 74 per cent of total affected. India, which saw cyclone Fani cause destruction in 2019, was the country most affected... read more

Recommended Practices

La gestión del riesgo de desastres suele contar con el apoyo de las tecnologías de teledetección durante las diferentes etapas de un desastre. Estas tecnologías junto con los datos geoespaciales encuentran su aplicación sobre todo durante la evaluación de riesgos, la elaboración de modelos de escenarios o la alerta temprana, a pesar de que las medidas preventivas también pueden apoyarse en estas innovaciones. Esta Práctica Recomendada de UN-SPIDER se centra en las medidas preventivas que pueden adoptarse de antemano, utilizando los datos de teledetección sobre las inundaciones y los datos...
