ACRI-ST is a member of the ACRI Group established in 1989, comprising companies that provide services the scope of which spans from satellite remote sensing, ocean & land surveys to hydraulic civil engineering through environmental research, computational fluid dynamics and dynamic similitude.
The ACRI group consists of a hundred people spread across all office sites. ACRI-ST, through its subsidiaries established in France and worldwide, is a supplier to space agencies (simulation of space-based sensors; operational chains development; processing, archiving and mission performance centres) and develops/operates environmental services, based on Copernicus-like data, to end users.
Born from a research company, ACRI-ST sustains a strong R&D in satellite remote sensing of the ocean, coastal waters, shoreline, continental waters, land cover and land use, as well as features and dynamics modelling and data assimilation in models. Innovation feeds the services in data collection, processing, archiving and distribution, in information design including environmental risk assessment, health changes and ecological mitigations (e.g. air quality, water quality, storm water collection – drainage – sewage, rivers restoration), as well as support to economic activities (e.g. aquaculture and shellfish farming, shipping and off-shore activities, insurance).
Within the group, ACRI-ST specializes in:
- Earth Observation (EO) mission specifications and End-to-End simulations; design of sensing equations, algorithm and data processor development; operation of components of EO mission Ground Segments
- Environmental monitoring – the so-called EO Mission user segments
- ITC research and data services for EO missions’ ground segments and environmental engineering
ACRI plays a role in the whole chain
- From sensors measurements’ specification
- To production of information of relevance to scientists, policy-makers, economic stakeholders,…
ACRI-ST has strong expertise in:
The Space and Ground Segment
Space domain sciences: studies and design of performance simulators of spatial systems in preparation of the use of remote sensing data for thematic applications related to the environment; prototyping data processing algorithms level 1, 2 and 3, and the analysis and exploitation of spatial missions; instrumental behaviour analysis, methodology and tool validation/calibration
Systems and Software engineering: operational chains development
PDGS & EO Data Operations Services: archiving and processing services (reprocessing) of space missions, mission performance centres operator
The Application Segment
Copernicus dynamics (modelling air quality and marine water), through ARGANS and ACRI-IN, for the management of industrial activity (e.g. aquaculture) or health information (e.g. prevention of peak pollution) or short and medium term impact (geophysics, hydrodynamics and coastal engineering).
