Balise PLB Jotron Tron SA20

Satellite transmission and guidance

Once activated, the Tron SA20 sends a distress message on 406 MHz with your position, then transmits a guidance signal on 121.5 MHz to help search teams get closer to you.

  • Cospas transmission-Sarsat 406.031 MHz with 5 W power
  • 121.5 MHz guidance signal for the approach phase
  • Multi-satellite GNSS receiver: GPS, GLONASS, Galileo
  • Visible and infrared flash for night-time detection
  • NFC connectivity with mobile application

Positioning is updated regularly, and the beacon is designed to maximize range with an extended antenna and a clear view of the sky.


Return Link function

Return Link Service (RLS) adds valuable feedback. It lets you know that your distress message has been received and routed to the SAR authorities, thanks to the Galileo system.

  • Visual confirmation via EPIRB indicator (if beacon is EPIRB coded)
  • Acknowledgement expected in less than 30 minutes, often in a few minutes
  • Important reminder: confirmation received does not mean help is already in the area
  • Position transmitted with beacon identifier

This confirmation helps to reassure you, especially when the situation is tense and every minute counts.
