The new W9xx platform developed by Wamblee offers the possibility of creating different types of emergency radio beacons in a compact and ergonomic enclosure. The architecture described below lends itself to different variations to meet specific customer needs.

General system architecture

Emergency Detection Module

  • Sensors (shock, immersion, tilt, temperature) or manual trigger.
  • Redundant activation logic to reduce false alarms.
  • Protection tab (1) against inadvertent activation.

Location Systems and Radio Transmission Units (4)

  • Integration with multi-band GNSS receivers to provide precise coordinates, with integrated anti-spoofing solutions.
  • Storage of the most recent position data before activation.
  • Periodic transmission of an encoded distress message.
  • Standardized or customized protocols for localization and unique device identification.

Antenna

  • Compact and protected antenna system (6).
  • Automatic deployment on self-inflating boats.

Power Supply

  • Long-life batteries (3) and minimal self-discharge. Specific solutions for operation in arctic temperatures can be adopted.
  • Intelligent energy management with “sleep” mode.

Casing and packaging

  • Structure resistant to shock, water, chemicals, and extreme temperatures (5).
  • Ergonomic design with visual and audible status indicators (2), which can be deactivated if necessary.

Mounting accessories

  • Various types of accessories (7) for mounting the device on inflatable rafts, suits, tactical clothing, etc.

Project Highlights

  • Simplified user interface
    • Simplified User Interface LEDs, vibrations, or audible signals confirm status (active, emergency, low battery) without the need for complex displays.
  • Functional Redundancy
    • MMultiple activation and verification mechanisms ensure operation even in extreme conditions.
  • Multi-Channel Communication
    • Multiple bands/protocols support to increase the likelihood of signal reception by rescue centers.
  • Advanced Energy Efficiency
    • Use of sleep scheduling techniques and ultra-low-power components to extend operational life.
  • Intelligent Self-Diagnostics
    • The device performs automatic self-test routines and notifies of any malfunctions before use.
  • High Electronic Integration
    • Optimized PCB to reduce weight and size, improving portability and robustness.
  • Secure Device Identity Management
    • Unclonable ID codes and tamper-resistant protocols.
