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>
