  • How ESA's Third Party Missions support European commercialisation

    ESA's Third Party Missions programme consists of Earth observation satellites that are owned by commercial and public organisations around the world.

  • Space data support Earth’s ecosystems

    ESA’s Earth observation (EO) missions are making a critical contribution to monitoring transformations in our planet’s ecosystems, helping track changes in the vegetation, soil, and ocean that affect these systems.

  • How to use space data to probe humankind’s ancient past

    Data disseminated by ESA’s Third Party Missions (TPM) programme are enabling archaeological investigations that could help to unravel the mysteries of past societies and cultures.

  • Commercial and international data for fire monitoring

    As climate change sparks a surge in the frequency and intensity of wildfires, satellite data disseminated through ESA’s Third Party Missions (TPM) programme are helping scientists to track and investigate these potentially damaging natural events.

  • TPM data help advance plastic litter detection from space

    Several innovative ESA Discovery element projects exploring remote sensing of plastic marine litter lean on commercial satellite data disseminated via the Agency’s Third Party Mission programme.

  • How satellite data empower sustainable urban growth

    Earth observation is a vital tool for facilitating the sustainable development of the world's cities, helping to ensure that urban centres keep spurring collaboration, innovation and opportunity as they continue to expand.

  • Satellites investigate Earth’s terrestrial hydrosphere

    ESA’s Earth observation satellites are playing a leading role in furthering our understanding of how Earth’s water cycle is being influenced by humankind.

  • ICEYE ESA archive collection now available to users

    ICEYE ESA archive collection is now available worldwide through ESA’s Third Party Missions programme. The ESA archive collections consist of products requested by ESA-supported projects worldwide, and, therefore, the products are scattered and dispersed over the territory in different time windows. The datasets regularly grow as ESA collects new products over the years.

  • How satellite data help to shape society

    Data from ESA’s Earth observation archives are improving understanding of the interactions between human activities and the environment, helping to power green economic development and boosting prosperity in Europe and beyond.

  • Very High Resolution data to take centre stage

    In the last few years, European New Space providers have helped strengthen the offering of very high resolution remote sensing data products—a designated workshop this November aims to focus on the latest developments in this arena.

  • Spot Extended Area mode added to ICEYE on-demand portfolio

    As an evolution of Spot mode, Spot Extended Area products are now available with the same resolution of Spot data (ground resolution of 1 m) but enabling to cover the area of 225 km2 (15 x 15 km) in a single SAR image.

  • New open-source Python library improves rapid mapping services

    In emergency services, rapid response is paramount. ICube-SERTIT’s Rapid Mapping Service provides near real-time delivery of geo-information to help emergency services respond quickly to disasters such as flooding, fires and landslides. A new Python open-source library, called EOReader, speeds up this mapping response by enabling the easy opening of imagery from multiple satellite sensors, both optical and synthetic aperture radar (SAR).

  • ICEYE, the World’s First SAR New Space Constellation

    ICEYE is a revolutionary Finnish company that developed and launched the world’s first under-100 kilogram synthetic-aperture radar (SAR) satellites into orbit.

  • ICEYE – A persistent monitoring SAR constellation

    Learn more about the ICEYE mission, a constellation of SAR satellites and part of ESA's Third Party Missions programme, in our latest infographic.

  • An overview of ESA's Third Party Missions programme

    ESA’s Third Party Missions programme consists of almost 50 satellite missions, which are owned by organisations around the world. ESA has agreements with these organisations to acquire, process, and distribute data from their missions

  • Φ-Week Triumphs

    In its fourth edition, Φ-Week presented the scientific community with amazing opportunities and projects—thus running alongside innovation at 360 degrees.

  • ICEYE full archive and tasking

    ICEYE full archive and new tasking products are available in Strip, Spot, SLEA (Spot Extended Area), Scan, and Dwell modes: Strip instrument mode: the ground swath is illuminated with a continuous sequence of pulses while the antenna beam is fixed in its orientation. This results in a long image strip parallel to the flight direction: the transmitted pulse bandwidth is adjusted to always achieve a ground range resolution of 3 m Spot instrument mode: the radar beam is steered to illuminate a fixed point to increase the illumination time, resulting in an extended Synthetic aperture length, which improves the azimuth resolution. Spot mode uses a 300 MHz pulse bandwidth and provides a slant plane image with a resolution of 0.5 m (range) by 0.25 m (azimuth); when translated into the ground, the products has 1 m resolution covering an area of 5 km x 5 km. Due to multi-looking, speckle noise is significantly reduced As an evolution of Spot mode, SLEA (Spot Extended Area) products are available with the same resolution of Spot data but a scene size of 15 km x 15 km Scan Instrument mode: the phased array antenna is used to create multiple beams in the elevation direction which allows to acquire a large area (100km x 100km) with resolution better than 15m. To achieve the finest image quality of its Scan image, ICEYE employs a TOPSAR technique, which brings major benefits over the quality of the images obtained with conventional SCANSAR imaging. With the 2-dimensional electronic beam steering, TOPSAR ensures the maximum radar power distribution in the scene, providing uniform image quality. Dwell mode: with the satellite staring at the same location for up to 25 seconds, Dwell mode is a very long Spot mode SAR collection. This yields a very fine azimuth resolution and highly-reduced speckle. The 25 second collection time allows the acquired image stack to be reconstructed as a video to give insight into the movement of objects. Two different processing levels can be requested: Single Look Complex (SLC): Single Look Complex (SLC) Level 1a products consist of focused SAR data geo-referenced using orbit and attitude data from the satellite and the scenes are stored in the satellite's native image acquisition geometry which is the slant-range-by-azimuth imaging plane and with zero-Doppler SAR coordinates. The pixels are spaced equidistant in azimuth and in slant range. The products include a single look in each dimension using the full transmit signal bandwidth and consist of complex magnitude value samples preserving both amplitude and phase information. No radiometric artefacts induced by spatial resampling or geocoding. The product is provided in Hierarchical Data Format (HDF5) plus a xml file with selected metadata Ground Range Detected (GRD): Ground Range Detected (GRD) Level 1b products consist of focused SAR data that has been detected, multi-looked and projected to ground range using an Earth ellipsoid model. The image coordinates are oriented along the flight direction and along the ground range. Pixel values represent detected magnitude, the phase information is lost. The resulting product has approximately square spatial resolution pixels and square pixel spacing with reduced speckle due to the multi-look processing at the cost of worse spatial resolution. No image rotation to a map coordinate system has been performed and interpolation artefacts are thus avoided. The product is provided in GeoTiff plus a xml file with selected metadata.

In addition, ICEYE has released a public catalogue that contains nearly 18,000 thumbnails under a creative common license of radar images acquired with ICEYE's SAR satellite constellation all around the world from 2019 until October 2020. Access to the catalogue requires registration. As per ESA policy, very high-resolution data over conflict areas cannot be provided.
