Comprised of three subsystems:

  1. Hydraulics: control buoyancy adjustment via an inflatable external bladder, so the float can surface and dive.
  2. Microprocessors: deal with function control and scheduling.
  3. Data transmission system: controls communication with satellite.

There are many float models in the Argo array. A few of the major ones are the PROVOR and the ARVOR built by NKE-INSTRUMENTATION in France in close collaboration with IFREMER, the APEX float produced by Teledyne Webb Research Corporation in the USA, the SOLO float designed and built by Scripps Institution of Oceanography in the USA, and the SOLO-II float built by MRV Systems in the USA.
