Status and Evolution of the Sentinel-1 Mission

2021 IEEE International Geoscience and Remote Sensing Symposium IGARSS, 2021
The routine operations of the Copernicus Sentinel-1 mission constellation are on-going and performed at full mission capacity. The C-band SAR mission is characterized by large-scale and repetitive observations, systematic production and free and open data policy. Sentinel-1 data are routinely used by Copernicus and many operational services, and in the

Analysis of Sentinel-1 mission capabilities

2009 IEEE International Geoscience and Remote Sensing Symposium, 2009
The Sentinel-1 mission is designed to be a source of continuous and reliable collection of C-band SAR imagery. Requirements for Sentinel-1 end to end system, as part of the complete family of GMES Sentinels, guarantee continuity of C-band SAR data and products availability to operational entities who exploit satellite radar imagery since ERS 1 ...

Sentinel-1 mission operations concept

2012 IEEE International Geoscience and Remote Sensing Symposium, 2012
In line with the overall Sentinel operations strategy, Sentinel-1, the next European C-Band SAR mission following ERS and ENVISAT, will be operated based on a stable and predefined observation scenario. During the Full Operations Capacity of the mission, this observation scenario will make optimum use of the SAR duty cycle within the technical ...

Cyclone Monitoring with Sentinel-1: Service Demonstration

2021 IEEE International Geoscience and Remote Sensing Symposium IGARSS, 2021
CYMS is an ESA-funded project aiming at scaling up an operational service for Tropical Cyclone monitoring, in view of its potential integration as part of a Copernicus Service. In 2020, the demonstration of such a service has been operated and user's requirements refined.

Sentinel-1 multitemporal SAR products

2015 IEEE International Geoscience and Remote Sensing Symposium (IGARSS), 2015
In this paper, we present a new framework for high-level processing of time series images, with particular reference to Sentinel-1 data. The proposed methodology has the goal of enhancing the interpretation of SAR imagery through the production of physical-based RGB composites, which are particularly suited for being easily interpreted by the human ...

FDBAQ a novel encoding scheme for Sentinel-1

2009 IEEE International Geoscience and Remote Sensing Symposium, 2009
Modern operational and/or high resolution SAR satellite missions impose stringent requirements on on-board data compression such as a higher data reduction ratio, more flexibility, and faster data throughput. A novel approach is Flexible Dynamic Block Adaptive Quantization (FDBAQ). This method outperforms currently used Block Adaptive Quantization with
