Visit the ACRI-ST

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 Copernicus services 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).

In 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
