Subsea Model 1020

Subsea's Model 1020 is a wireless, medium range communication board set specifically designed to fill custom underwater communications requirements. The design is ideal for custom communications requirements in ADS (one atmosphere diving suits) and small submersibles where space is at an absolute premium . The Subsea Model 1020 gives the user complete freedom to design in a custom communications package for their specific design needs.

Subsea’s Model 1020, is unequalled in the industry in terms of:

  • Clear communications in strong currents and around obstacles
  • Compact size, H = 5.5cm, L = 15.3cm, W = 7.6cm, in the smallest configuration
  • Voice-activated (VOX) or push-to-talk (PTT), selectable by the user
  • Pinger mode for location or emergency situations
  • Range of up to 3 km at 27 kHz
  • Ease of integration and use
  • Reliability in professional use
  • Many frequency options available

Advanced technology contributes to the superior quality of communications from the Subsea Model 1020. Sophisticated electronic circuitry and filtering techniques are utilized to enhance speech clarity and reduce extraneous noises, thereby providing optimum clarity under adverse conditions. The Subsea Model 1020 — like all of Subsea Import's products — employs crystal-controlled single side band (SSB) ultrasonic techniques. Subsea’s SSB technology provides distortion free transmissions and extended battery life. Operators will enjoy clear communications even in strong currents or waters crowded with ships and obstacles.

The Subsea Model 1020 is designed for user defined, custom communications requirements, where the user requires the flexibility of a custom integrated system such as in ADS and small submersibles where space is at a premium.
