Environment & Climate Monitoring

Worldwide tracking and environmental monitoring by satellite
Sustainable development, combating global warming, and managing natural resources are major challenges for the international community. At CLS, we support environmental conservation and sustainable development policies. Our experts provide integrated solutions using the latest space technologies, including equipment, services, and expertise.
With over 30 years of collaboration with scientists dedicated to studying and protecting our planet, our solutions enable the collection of vast amounts of data on wildlife, oceans, inland waters, ice, and climate, as well as on the impact of human activity on nature.
These satellite tools and services offer the international community effective solutions for:
Biodiversity Protection
As the historical operator of the Argos data collection and localization system and exclusive provider of Argos value-added services, we offer connectivity services and enriched data fusion through artificial intelligence solutions to scientists worldwide.
Our mission is to support the international community in studying and protecting biodiversity. The Argos system is one of the few to offer global coverage with a wide range of transmitters suitable for monitoring wildlife and flora. Our solutions also allow you to connect your tracking beacons to new technologies.


Smart Agriculture
With the global population expected to reach 9 billion by 2050, food production will need to increase by 70% to meet future demand. However, the planet’s natural resources are limited, meaning innovation must start now.
It has never been more crucial to have information on measures such as water consumption, soil quality, equipment efficiency, and herd monitoring. Our teams support agricultural producers by providing multi-source solutions to maintain soil quality, reduce erosion, sustainably manage water resources and irrigation, and raise livestock in an environmentally friendly manner.
Our key solutions enable better decision-making and land cultivation while preserving the planet’s resources. Connected sensors, data on land use and soil quality, reliable and user-friendly connectivity, and decision-support platforms are among the components we master and make available to agricultural stakeholders.
Fighting Pollution
Pollution is a global issue affecting land, air, and water, destroying the environment and contaminating our food and water.
We offer real-time pollution monitoring solutions using specialized equipment and custom drift models. These tools enable field cleanup teams to optimize decontamination efforts and protect vulnerable marine and coastal areas.
This versatile solution can be adapted to monitor various types of pollution, such as plastic, oil, air, or even harmful algae like sargassum.

Herd Management
Our telemetry experts, with over 40 years of experience in Argos satellite tracking and spatial data integration, offer a dedicated Argos solution for managing wild, semi-wild, and farmed herds.
This solution combines satellite tracking, Earth observation, and data from other space systems to support livestock farming, species reintroduction, and protection in remote areas. We provide observations on animals, their habitats, and living conditions. These data, integrated into our “livestock” databases, are transformed into actionable information for sustainable management tailored to each user’s specific needs.
Oceanography, Meteorology, Glaciology
Scientists, oceanographers, meteorologists, glaciologists, climatologists, and marine and environmental specialists increasingly rely on satellite systems to collect in situ data.
These data are crucial for improving our understanding and protection of the planet, as well as for comprehending ocean-atmosphere interactions. Argos modems, associated connectivity, complementary data (radar, optical, etc.), and CLS platforms for data visualization and interpretation are custom tools developed by our experts for the international scientific community.
They enable quick and easy connection of new technologies and offer data services for a wide range of applications.

Sustainable Water Resource Management
Water resources, infrastructures, natural hazards, climate change, and food security: CLS provides reliable and precise data from in situ and satellite observations, tailored to each need and issue. This enables better water resource management.
For sustainable water resource management, CLS offers complementary, innovative, and independent solutions that adapt to your territories and address your challenges.
Sustainable Forest Resource Management
Forests are essential for the planet’s well-being. As oxygen sinks, they purify the air, house more than three-quarters of terrestrial biodiversity, and help combat climate change.
Preserving forests is a priority for CLS experts, who have conducted hundreds of projects in Africa, South America, and Europe.
Our forest management solutions include:
- Dynamic forest assessment: estimating vegetation cover area, measuring forest loss and gain, establishing forest composition.
- Monitoring forest disturbances: tracking forest health, mapping emergency situations and damage caused by windthrows, fires, landslides, etc.


Land Management and Combating Land Artificialization
In France, land artificialization exceeds the European average, with 20,000 hectares of land artificialized each year since 2006.
Stakeholders need precise, objective, qualitative, dynamic, and land-based knowledge of their territory, as well as reliable data on artificialization and pressure on agricultural, natural, and forest areas.
Our experts provide these strategic data for effective, resilient, and tailored management for each territory to hundreds of clients worldwide.
Our solutions include:
- Land use at all scales (large and small)
- Historical, current, and prospective mapping
- Detection of renaturation and artificialization potentials
- Databases on usage evolution, land consumption, and statistics.
Our teams deliver ultra-precise maps adjusted to each type of territory’s issues throughout the year.
Risk Management
Humanitarian crises, floods, fires, volcanic eruptions, earthquakes, extreme natural, industrial, or geopolitical events are numerous. With over 10 years of involvement in the CEMS mapping service, CLS has all the necessary tools to create, aggregate, and disseminate information in case of disasters.
Using multi-source data, our experts can provide:
- Analysis, mapping, and modeling aimed at limiting and preventing risks.
- Monitoring and evaluation of the context during emergency interventions to contribute to disaster relief efforts.
- Damage assessment after the event, impact analysis, and reconstruction modeling for post-crisis support.
CLS quickly provides all information, which is accurate, high-quality, and standardized.
