• Organization of communication in intermediate layers of water
  • The connecting wires and the overall dimensions
  • Possible to conveniently place the radio station modules in the aqualung

 

Major advantage IVA S/W:

  • Voice and data transmission at distance of up to 500 meters for line if sight underwater communications
  • Additional antenna for transferring data at distance of up to 60 m from one media to another (water-air-ice)
  • Organization of communication in intermediate layers of water as well as in the coastal zone in the conditions of external disturbance and noise
  • Communication range independent from the hydrological heterogeneities on the signal propagation
  • Ability to bypass obstacles to the signal propagation

 

Possible applications:

  • Shelf research and investigation of new under water mineral deposits
  • Arctic development
  • Monitoring of the situation in coastal zones
  • Repair, technical. maintenance and modernization of stationary underwater structures
  • Prophylaxis and prevention of emergencies in the oil/gas production areas
  • Development of underwater unmanned vehicles
  • Protection of the water-naval bases
  • Communication in the reconnaissance group of combat swimmers
