MetOcean, FSU Collaborate on STOKES Iridium Drifter

MetOcean Telematics announced the development of the

STOKES Iridium tracking drifter. The STOKES drifter was designed and tested in technical partnership with Florida State

University (FSU). The STOKES drifter is a compact drifting buoy which tracks water currents at the surface. The small light-weight buoy is equipped with Iridium satellite telem- etry, GPS positioning, and a sea surface temperature sensor.

Iridium satellite telemetry enables the buoy to provide vital sensor and geo-positional location data in real time. Iridium also allows the buoy to have bi-directional capabilities. This is a critical ability, for example, if the buoy enters a region of in- terest the end-user can communicate with the unit by sending it a command to change reporting intervals or request essential time sensitive data. The applications for the STOKES are
