SC 40 A - AG - IG

These drifters are used mostly offshore in order to monitor the current at sea surface for oceanographic studies and also the oil spill trajectories

These drifters are used mostly offshore in order to monitor the current at sea surface for oceanographic studies and also the oil spill trajectories. The drifters can be fitted with holey-sock drogue and are, by this way, linked to a particular mass of water. The drag ratio between surface buoy and the drogue validates the good function of current follower. If no drogue is mounted, the drifter is affected by the surface current.

The SC 40 buoy is a sphere of 400 mm diameter, molded in plastic at high pressure. The SC40 is with low radar echo in order to reduce the risk to be picked up by fishermen and is fitted with lashing rings. nke Instrumentation proposes 3 models:

  • SC 40 A : data are collected by Argos satellites, position is achieved by Doppler effect computed by CLS
  • SC 40 AG: data are collected by Argos satellites, position is acquire by a GPS receiver and transmitted via Argos.
  • SC 40 IG : data are collected by Iridium satellites, position is acquire by a GPS receiver and transmitted via Iridium.

Main features

  • 3 models : GPS receiver and ARGOS transmission ; ARGOS satellite for data collection and localization GPS receiver with Iridium transmission
  • Very simple to use
  • In option "holey-sock drogue" and various length of line
  • Easy BT connection for parameters setting
  • Lithium and alkaline battery solutions
  • 40 cm diameter spherical buoy
