Sentinel-1A Product Geolocation Accuracy: Commissioning Phase Results
Sentinel-1A (S1A) is an Earth observation satellite carrying a state-of-the-art Synthetic Aperture Radar (SAR) imaging instrument. It was launched by the European Space Agency (ESA) on 3 April 2014. With the end of the in-orbit commissioning phase having been completed at the end of September 2014, S1A data products are already consistently providing highly accurate geolocation. StripMap (SM) m...
متن کاملSentinel-1A/B Combined Product Geolocation Accuracy
Sentinel-1A and -1B are twin spaceborne synthetic aperture radar (SAR) sensors developed and operated by the European Space Agency under the auspices of the Copernicus Earth observation programme. Launched in April 2014 and April 2016, Sentinel-1A and -1B are currently operating in tandem, in a common orbital configuration to provide an increased revisit frequency. In-orbit commissioning was co...
متن کاملASAR Product Consistency and Geolocation Accuracy
The ability to geolocate ENVISAT ASAR image products and transform them into a map projection is a critical step required to enable not only overlays with other sources of information (e.g. DEM, GIS layers), but even with other ASAR products, especially those acquired with a different track, beam, or incidence angle. This paper summarises geolocation validation results evaluating both the relat...
متن کاملSentinel-1A – First precise orbit determination results
Sentinel-1A is the first satellite of the European Copernicus programme. Equipped with a Synthetic Aperture Radar (SAR) instrument the satellite was launched on April 3, 2014. Operational since October 2014 the satellite delivers valuable data for more than two years. The orbit accuracy requirements are given as 5 cm in 3D. In order to fulfill this stringent requirement the precise orbit determ...
متن کاملFirst Results from Sentinel-1A InSAR over Australia: Application to the Perth Basin
Past ground-based geodetic measurements in the Perth Basin, Australia, record small-magnitude subsidence (up to 7 mm/y), but are limited to discrete points or traverses across parts of the metropolitan area. Here, we investigate deformation over a much larger region by performing the first application of Sentinel-1A InSAR data to Australia. The duration of the study is short (0.7 y), as dictate...
