Gmes Sentinel-1 Mission and System
نویسندگان
چکیده
The ESA Sentinels constitute the first series of operational satellites responding to the Earth Observation needs of the EU-ESA Global Monitoring for Environment and Security (GMES) programme. The GMES space component relies on existing and planned space assets as well as on new complementary developments by ESA. This paper describes the Sentinel-1 mission, an imaging synthetic aperture radar (SAR) satellite constellation at C-band. It provides an overview of the mission requirements, its applications and the technical concept for the system.

متن کاملSvalex 2005 and Icesar 2007 - Two Flight Campaigns over Sea and Land Ice in the Svalbard Region: Sea Ice Studies
Flight campaigns named SVALEX (Svalbard Experiment) and ICESAR (Synthetic Aperture Radar for Ice) were carried out over sea and land ice around Svalbard in winters 2005 and 2007, respectively. Here we report on the sea ice part of these campaigns. The objectives were to collect data for studying the effect of sea ice roughness on the atmospheric boundary layer, and for investigating the retriev...
متن کاملEstimation of Soil Moisture Index Using Multi-Temporal Sentinel-1 Images over Poyang Lake Ungauged Zone
The C-band radar instruments onboard the two-satellite GMES Sentinel-1 constellation provide global measurements with short revisit time (about six days) and medium spatial resolution (5 × 20 m), which are appropriate for watershed scale hydrological applications. This paper aims to explore the potential of Sentinel-1 for estimating surface soil moisture using a multi-temporal approach. To this...
