ARGANS is a small, independent company which has been in business since 2007. During this time, we have undertaken a number of projects with the European Space Agency and the European Commission; we have been part of large consortiums, undertaking both long and short term projects with values ranging from a few thousand to a few million euros. In addition, we work in collaboration with UK Government Agencies and international. We have also developed our own tools and software as part of smaller projects which we manage in-house.

Sentinel Mission Support
The ESA Sentinel satellite missions carry a range of technologies such as radar and multi-spectral imaging instruments for land, ocean and atmosphere monitoring. Along with contributing missions from other space agencies they form the space component of Copernicus, the European Commission Earth observation program.
ARGANS has been involved in the Sentinel program in a variety of roles. As prime contractor leading the development of prototype processors of Level 2 data for the Sentinel 3 optical sensors and the development of the Online Sentinel handbook. As partner ARGANS has roles in Sentinel 2 and Sentinel 3 Mission Performance Centres (MPC).
SMOS Mission Support
ESA's Soil Moisture and Ocean Salinity (SMOS) satellite is an Earth Explorer mission component of the Living Planet Programme. It was launched in November 2009 and is dedicated to making global observations of soil moisture over land and salinity over oceans.
ARGANS is the prime contractor for the Level 2 ocean salinity component and has supported ESA before launch, during commissioning and throughout operation in the development and maintenance of the L2OS processor in collaboration with Expert Support Laboratories (ESL). Building on expertise in SMOS derived ocean salinity ARGANS was awarded in 2015 to assess the capabilities of SMOS to detect rainfall over the oceans. read more
RESMALI Marine Litter Detection
Ocean plastic debris is a serious problem for the environment, and ESA is one of the many organisations taking steps to understand it's impact.
ARGANS recently partnered with ESA and other organisations to investigate the feasibility of using remote sensing methods to identify this debris from orbit. This can potentially assist in allowing a greater targeting of efforts in combating this issue, and support pressing observational needs for marine litter global monitoring.
Salinity Climate Change Initiative
The ESA Climate Change Initiative programme aims to establish climate data records (CDR) for Essential Climate Variables (ECV) to monitor changes to the Earth's climate. One such ECV is sea surface salinity, used to estimate oceanic transport of freshwater and changes in the global water cycle.
ARGANS, in association with international scientific organisations, is contributing to this program in a project to provide decadal time-series of sea surface salinity acquired by the ESA SMOS satellite, launched 2009, along with NASA Aquarius (2011-2015) and SMAP, launched in 2015. read more
DIMITRI Development & Support
DIMITRI (Database for Imaging Multi-spectral Instruments and Tools for Radiometric Inter-comparison) is a database containing Level 1 radiometric measurements from various optical sensors over terrestrial targets selected as calibration sites due to having stable radiometric properties and observing conditions.
DIMITRI provides tools to allow inter-comparison of sensor data for purposes of calibration, validation and correction of aerosol scattering and glint reflection. ARGANS is involved in a number of DIMITRI projects ranging from algorithm development for new methodologies and tools, collection and ingestion of sensor data into the database, and verification and dissemination of outputs to the scientific community. read more
Sen2Coral Sentinel-2 & Coral Reefs
The objective of ESA’s SEOM Programme Sen2Coral is the preparation of the exploitation of the Sentinel-2 mission for coral reefs by developing and validating appropriate, open source algorithm available for the community.
The project objectives are the scientific exploitation and validation of the Sentinel-2 Multispectral Instrument (MSI) for mapping (habitat, bathymetry, and water quality) and detection change for coral reef health assessment and monitoring, and algorithm development dedicated to Sentinel-2 capabilities to satisfying these objectives. Coral reefs mortality changes, which are strongly influenced by the El Nino phenomenon, are accurate markers of the Global Warming. read more
Satellite Derived Bathymetry (SDB) & Nautical Chart Production
Coastal waters are dynamic and changing environments. Monitoring and measuring water depth is crucial for the safety of navigation and the integrated coastal zone management (ICZM). Deriving bathymetry from satellite has key benefits being more cost effective, available for remote and inaccessible areas and quicker to delivery than traditional methods.
ARGANS has developed innovative methodologies for generating IHO-compliant nautical charts derived from satellite multi-spectral images processed using an adaptive look-up table physics-based inversion technique, with the assistance of one of our collaborators, under contract to the French Hydrographical & Oceanographic Office (SHOM).
European Commission Horizon 2020 project (ec.europa.eu) to facilitate access to Earth Observation data and pre-processing tools by the coastal and oceanic research community, towards the future provision of services based on EO data, namely (but not restricted to) Coastal Waters research. [2016-2019].
ESA contract involving a consortia led by ARGANS providing support needed for updating and validating algorithms to be used in the processor for the 4th Reprocessing of MERIS data intended to facilitate a smooth transition towards Sentinel-3 products.
ARGANS provides technical support to ESA in activities involving the International Disaster 'Space & Natural Disasters and CEOS Working Group Disasters. This involves co-ordinating activities and initiatives related to the use of satellite EO to support geohazards, monitoring the user community, collecting and analysing performance metrics, preparing dissemination material and performing outreach activities [2014-2020]. During the period 2018-2019 ARGANS also supports the French Space Agency (CNES) in its lead role within the Executive Secretariat and the Board of the International Charter.
European Commission project (www.sensyf.eu) delivering scalable, cloud-based processing, ease of access to Copernicus data and sandbox for developing services. ARGANS service was an industrialised version of the DIMITRI optical sensor inter-comparison and analysis tool [2013-2015].
European Commission R&D project focused on ocean biogeochemical properties and the assimilation of multi-spectral satellite data and in-situ geophysical measurements into biogeochemical models [2012-2014].
As a partner in ESA's EO Services for Ecosystem Validation project ARGANS provided technical and consulting support towards the development of multispectral products showing: bathymetry and water quality, vegetation & marine habitat changes over time and vegetation health and productivity [2012-2014].
Under the Instrument Data quality Evaluation and Analysis Service (IDEAS) consortium ARGANS were responsible for leading the Sensor Performance & Product (SPPA) Assessment Optical Instruments Group and responsible, with sub-contractor support, for QC activities involving satellite missions: ENVISAT MERIS, Landsat, SeaWiFS and MODIS [2008-2013].
ESA satellite earth observation missions are 'big science' projects financed by member states' governments and receiving equivalently valued high-tech contracts through the industrial 'GeoReturn' policy and consequently projects tend to be undertaken by pan-European consortia.
ARGANS has forged strong partnerships through joining consortia both as prime and sub-contractor with UK, European and International entities: companies, research institutes, universities and individual scientific consultants. Link to subcontactor GDPR notice
ARGANS has a staff of skilled and multi-disciplinary engineers and scientists who undertake multiple roles within the company both project management and technical. This core staff are supplemented as needed by external consultants and collaboration with the parent company ACRI-ST.
