Technology (NIOT) has successfully indigenously developed the Lagrangian
drifter buoy which is built with geostationary based Indian satellite communication
module for Meteorological/Oceanographic applications and it has been named Pradyu.
The drifter buoy-Pradyu has been successfully interfaced with NTC type Sea
Surface Temperature (SST) sensor, Smart GPS receiver, INSAT communication modem
and designed with holy sock drogue acting as the sea anchor which was
fabricated using nylon collapsible cordura material. Drifter buoy was indigenized
following internationally accepted measurement scheme and data transmission
protocol, which are mandatory on usage of data by international scientific
community. This article consists of the design and field validation performed
to evaluate in-house developed spherical Lagrangian drifter buoy.</span
