RESTEC has released a new version (version 2.0) of VEGA*1. Version 2.0 included the observation data by Sentinel-1 which carries the Synthetic Aperture Radar (SAR) in addition to the existing optical satellites.
Sentinel-1 is developed and operated by the European Space Agency (ESA) and Sentinel-1A and 1B were launched in 2014 and 2016 respectively. ESA announced the end of the mission for 1B in 2022 but plans to launch 1C in 2023. SAR satellites can obtain information on the ground surface despite cloudy weather as SAR uses radio wave which penetrates clouds.
This improvement makes it possible to visualize almost a 10-year archive of SAR data from 2014 to date. Users can also visualize optical data observed by Landsat-4, 5, 7, 8, 9, and Sentinel-2.
