About new developed remote sensing satellites

There have been several new remote sensing satellites developed in recent years, offering improved capabilities and applications in various fields. Here are a few examples:

  1. NASA's Landsat 9: Launched in September 2021, Landsat 9 is a joint mission with the US Geological Survey (USGS) to provide high-resolution imagery of the Earth's surface. It features a new instrument called the Operational Land Imager 2 (OLI-2), which provides improved spectral resolution and increased spatial resolution.
  2. European Space Agency's (ESA) Copernicus Sentinel-6: Launched in November 2020, Sentinel-6 is a radar altimeter satellite designed to measure sea level rise and ocean currents. It provides high-resolution data on ocean topography, sea ice, and ocean currents.
  3. China's Gaofen-7: Launched in June 2020, Gaofen-7 is a high-resolution optical satellite designed for land and ocean monitoring. It features a 1-meter resolution panchromatic camera and 4-meter resolution multispectral camera.
  4. India's Cartosat-3: Launched in December 2019, Cartosat-3 is a high-resolution optical satellite designed for land and ocean monitoring. It features a 0.25-meter resolution panchromatic camera and 1-meter resolution multispectral camera.
  5. NASA's Surface Water and Ocean Topography (SWOT) mission: Scheduled to launch in 2022, SWOT is a joint mission with the French space agency CNES to study the Earth's surface water and ocean topography. It will provide high-resolution data on ocean currents, sea level rise, and lake and river dynamics.
  6. ESA's Biomass mission: Scheduled to launch in 2023, Biomass is a mission designed to study the Earth's forests and biomass. It will use a radar instrument to measure forest biomass and carbon stocks.
  7. China's Ziyuan-16: Launched in December 2020, Ziyuan-16 is a high-resolution optical satellite designed for land and ocean monitoring. It features a 1-meter resolution panchromatic camera and 4-meter resolution multispectral camera.
  8. Russia's Resurs-P: Launched in 2016, Resurs-P is a high-resolution optical satellite designed for land and ocean monitoring. It features a 1-meter resolution panchromatic camera and 4-meter resolution multispectral camera.
  9. South Korea's Kompsat-3: Launched in December 2019, Kompsat-3 is a high-resolution optical satellite designed for land and ocean monitoring. It features a 0.5-meter resolution panchromatic camera and 2-meter resolution multispectral camera.
  10. Japan's ALOS-4: Scheduled to launch in 2023, ALOS-4 is a high-resolution optical satellite designed for land and ocean monitoring. It features a 0.3-meter resolution panchromatic camera and 1-meter resolution multispectral camera.
