TERRA Demonstrator 1 Completes First USV Test Mission in the Sperchios River, Greece
On 4 March, the TERRA project team successfully carried out the first test run of the Unmanned Surface Vehicle (USV) developed for Demonstrator 1, marking an important milestone in the project’s efforts to advance environmental monitoring and climate services.
During this initial field deployment in the Sperchios River in central Greece, the USV successfully navigated the river environment and collected its first set of water pollution monitoring data. This test confirmed the operational readiness of the system and represents a key step toward the implementation of the Demonstrator.
The USV is a core component of TERRA’s Demonstrator 1, designed to support advanced monitoring of water pollution and environmental conditions in the Sperchios Gulf region. The platform is equipped with IoT-based water quality sensors capable of collecting in-situ measurements that complement Copernicus satellite observations and hydrological modelling tools developed within the project.
By combining in-situ sensor measurements, Earth Observation data, and advanced analytics, TERRA aims to improve the understanding of pollution dynamics and support more effective environmental management of coastal and river systems.
This first field mission validated that the USV platform has been successfully assembled and can operate effectively in real river conditions. The test also allowed the technical team to verify the system’s data collection capabilities and evaluate the vehicle’s trajectory and navigation performance during the mission.
In the coming months, additional missions will be conducted, enabling the collection of further environmental datasets. These data will support the training of forecasting and Machine Learning models, which will be integrated into the TERRA platform to enhance pollution monitoring and predictive capabilities.
Future developments will also focus on upgrading the USV with autonomous navigation features, including obstacle detection and avoidance, allowing the vehicle to operate with greater autonomy and efficiency during environmental monitoring missions.
The successful completion of this first test mission represents an important step toward the full operational deployment of Demonstrator 1, bringing TERRA closer to delivering integrated, data-driven climate services for water and coastal management.
