Main features:
- Very simple to use
- In option: “holey socks drogue” and various length of line
- Easy BT connection for parameters setting
- Lithium and alkaline battery solutions
- 40cm diameter spherical buoy
- Based on our WiSens technology
The data provided by the SC40 – SVP BRST will serve as calibration and validation of accurate satellite HRSST retrievals from the Copernicus Sentinel-3 SLSTR. The project will further assess the suitability of drifting buoys to provide Fiducial Reference Measurements.
