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 ...

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

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.

Prospects of Sentinel-1 for land applications

2012 IEEE International Geoscience and Remote Sensing Symposium, 2012
The Sentinel-1 mission is a polar-orbiting satellite constellation for the continuation of C-band Synthetic Aperture Radar (SAR) applications. Contrary to its predecessor instruments onboard of ENVISAT and RADARSAT, the Sentinel-1 satellites will be operated following a predefined and fixed baseline acquisition scenario.

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

Assessment of sentinel-1 radiometric stability and quality

2017 IEEE International Geoscience and Remote Sensing Symposium (IGARSS), 2017
The main goal of this paper is to assess the radiometric stability of the new Sentinel-1A (S-1A) SAR (Synthetic Aperture Radar) sensors. The S-1A radiometric stability was assessed by analyzing the temporal variations of the backscattering coefficient (σ°) returned from invariant targets. The results show three stable sub-time series of S-1A data.

Surface Water Detection from Sentinel-1

2021 IEEE International Geoscience and Remote Sensing Symposium IGARSS, 2021
Synthetic Aperture Radar (SAR) data from Sentinel-1 mission is a valuable all-weather observation for various monitoring applications on the land surface. In particular, SAR observations have unique signatures over surface water which makes them appropriate to develop a global surface water monitoring system. Existing global surface water products rely

GMES Sentinel-1 mission

Remote Sensing of Environment, 2012
Abstract In the frame of the Global Monitoring for Environment and Security (GMES) Space Component programme, the European Space Agency (ESA) undertook the development of a European Radar Observatory (Sentinel-1), a polar orbiting two-satellite constellation for the continuation and improvement of SAR operational services and applications.
