End of Mission for Sentinel-1B

On 23 December 2021, Copernicus Sentinel-1B experienced an anomaly related to the instrument electronics power supply provided by the satellite platform, leaving it unable to deliver radar data. Since then spacecraft operators and engineers have been working tirelessly to rectify the issue. Unfortunately, despite all concerted efforts, ESA and the European Commission announce that it […]Read More

SAR for change detection in Mariupol

Synthetic Aperture Radar (SAR) from space is particularly well suited for change detection on the ground. With its ability to look through clouds and darkness, SAR remote sensing consistently produces high quality, well calibrated imagery with good geolocation accuracy. This article is part of our series on SAR space data applications and our series on […]Read More

SAR Satellites for Agriculture

Synthetic Aperture Radar (SAR) imaging from space is in its golden age. With an increasing number of space-based SAR sensors in operation, and an increasingly growing temporal and spatial resolution, combined with the characteristics of SAR: independent from daylight, cloud coverage and weather conditions, we are seeing a fast growth of applications. One of the […]Read More

20 Space Acronyms That Help Farmers

Agriculture is one of the key application areas of satellite data. We have all heard about precision farming using satellite navigation signals and a large array of Earth Observation techniques that help farmers identify soil characteristics and crop health. In this article we describe these techniques in a list of space data ‘indices’ that describe […]Read More

SAR in Support of the War in Ukraine

Radar satellite imagery (SAR) offers great opportunities for assisting humanitarian operations during war, offering support to displaced people in their own and in hosting countries, like the current situation in Ukraine. It helps relief organizations to closely follow the number of people in need and their locations, by monitoring the areas affected by the war. […]Read More

SAR Satellites for Flood Monitoring

One of the biggest challenges of climate change is water-related. Flooding of cities is a natural hazard that occurs in many countries worldwide, generating economic, material and human loss. These floods bring misery to those that live in the areas affected. Water can come into people’s houses, pollute drinking water, break down electricity supply, block […]Read More

Change Detection in Cities Using SAR Images

The rise in population in the last 100 years has led to a rapid expansion of the world’s cities.  As a consequence, there are big infrastructure developments and construction projects, leading to urban change, which requires monitoring. Similarly, natural disasters or war can cause quick changes to a city infrastructure. Remote sensing by imaging radar […]Read More

Interpreting SAR Satellite Images

The interpretation of Synthetic Aperture Radar (SAR) satellite images involves the identification and measurement of targets in a radar image. This radar image is the result of extensive data processing, including calibration, geometric, and radiometric corrections. Analysing SAR images: finding your targets A target may be any feature or object which can be observed in […]Read More

The end of Sentinel-1B?

The situation “does not look very good” for the Sentinel-1B satellite of the EU’s Copernicus Earth observation programme, confirmed European Space Agency (ESA) Director General Josef Aschbacher and Simonetta Cheli, head of ESA’s Earth observation programmes, at the end of the institution’s Council meeting on Thursday 17 March. Official update from ESA This remark came shortly after […]Read More

ITT: SAR/GALILEO Return Link Service Evolutions

The European Commission has launched an Invitation to Tender (ITT) to set up a system prototype demonstration of the SAR/Galileo return link service two-way messaging services and develop and validate a prototype of Second Generation Beacon. The total estimated contract value is EUR 700,000 and the deadline for submission is 8 October 2020 16:00. Full […]Read More
