Sentinel-1 Satellite Evolution

IGARSS 2018 - 2018 IEEE International Geoscience and Remote Sensing Symposium, 2018
The paper provides the overview of the evolution of the Copernicus Sentinel-l Space Segment and the Spacecraft development status. Following the successful launch and in-orbit Commissioning of Sentinel-1A in 2014 and Sentinel-1B in 2016, ESA is currently developing the Sentinel-1C and −1D models.

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.

Sentinel-1 Ground Segment

2012 IEEE International Geoscience and Remote Sensing Symposium, 2012
This paper provides an overview of the Senitnel-1 Ground Segment and its main operations concepts. It presents the Sentinel-1 Payload data Ground Segment (PDGS), responsible during the Sentinel-1 mission operations for the Sentinel-1 mission planning, X-Band data downlink, data processing, quality performance, data dissemination, archiving activities ...

GMES Sentinel-1 FDBAQ performance analysis

2009 IEEE Radar Conference, 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

Irrigation Mapping Using Sentinel-1 Time Series

IGARSS 2020 - 2020 IEEE International Geoscience and Remote Sensing Symposium, 2020
The obj ective of this paper is to present an approach for mapping irrigated areas at plot scale using the Sentinel-1 radar time series. Over a study site located in Catalonia region of north Spain, a dense temporal series of S1 backscattering coefficients were first obtained at plot scale and grid scale (10km x 10km).

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 ...

Sentinel-1 CSAR mission status

SPIE Proceedings, 2009
The Sentinel-1 synthetic aperture radar (SAR) constellation represents a completely new approach to SAR mission design by ESA in direct response to the operational needs for SAR data expressed under the EU-ESA Global Monitoring for Environment and Security (GMES) programme. The Sentinel-1 constellation is expected to provide near daily coverage over

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 ...
