No signal? We fly it in.

Autonomous. Long range. A repeater on board.

The Problem

Communication in obstructed terrain is unreliable.

Handheld radios lose effectiveness when terrain blocks the signal path. In search and rescue, communication gaps delay decisions, split teams, and reduce situational awareness.

111 Million acres where a permanent repeater cannot be built

The National Wilderness Preservation System covers 806 areas across more than 111 million acres. Federal law generally prohibits structures and installations inside them. Fire crews still work there, and so do the people who go missing there.

The Solution

A drone that becomes the missing link.

The system uses a drone as a temporary elevated repeater platform. Once positioned on a high point, it creates a relay path between operators who cannot directly reach each other.

  • Rapid deployment
  • Elevated relay position
  • No permanent infrastructure
  • Improved field coordination
  • Portable emergency use

How It Works

From blocked signal to restored communication.

01

Deploy

The team launches or places the drone near the obstructed area.

02

Position

The drone lands at an elevated ridge, hill, or structure.

03

Relay

The repeater receives and retransmits communication between separated teams.

04

Coordinate

Search teams regain radio contact and maintain better situational awareness.
