The WAVY Drifters Family is ready to be deployed


During 2021, the team was able to successfully conclude the development of the WAVY Ocean, which has been tested for several use cases, and it is now nearly ready for production. 

The WAVY Ocean is the largest drifter of the WAVY family, a 20 cm sphere with 3450g weight, designed for coastal, shelf, deep sea, and long-lived missions. It is equipped with GNSS tracking geo-spatial positioning, 2 temperature sensors acquiring both sea surfer and near sea surface temperatures gradient, and an Inertial Motion Unit (IMU) that together with the GNSS provides directional waves. In its present configuration, this drifter acquires temperature data every 20 minutes, and wave parameters at 4Hz every 1 to 5 hours. It communicates via satellite and, depending on the WAVY configurations, the battery life time can last up to 140 days. 

The family of WAVY drifters is now composed of tree drifters tested and demonstrated in many different campaigns: the WAVY Basic, the WAVY Littoral, and the WAVY Ocean.
