Search & Rescue Technology
Off-Grid Coordination.
Real-Time Rescue.
MeshCore SAR transforms smartphones into powerful mesh-networked coordination tools for search and rescue teams operating beyond cellular coverage.
Built for Search & Rescue
Every feature designed with field operations in mind. Stay connected when it matters most.
Mesh Communication
Works with MeshCore companion radios via Bluetooth. Messages automatically route through the mesh network, reaching team members even when direct radio contact fails.
Live Team Map
Real-time GPS positions of all connected team members. Battery status, signal strength, and distance displayed at a glance.
SAR Markers
One-tap markers for critical events: Found Person (green), Fire/Hazard (red), Staging Area (orange). Share instantly over mesh.
Offline Maps
Pre-download regions before deployment. Supports OpenStreetMap, OpenTopoMap, satellite imagery, and government WMS layers.
Map Drawings
Draw lines and rectangles directly on the map. Share search sectors and boundaries with your team over the mesh network.
Message Echo Detection
Know when your broadcast reached the network. Visual confirmation when mesh nodes rebroadcast your messages.
How Mesh Networking Works
Create resilient communication networks without cellular infrastructure. Messages hop through relays to reach distant team members.
Connect
Pair your phone with a MeshCore radio via Bluetooth. Simple setup, no configuration required.
Broadcast
Send messages and GPS coordinates over the mesh network. Your location updates automatically.
Relay
Nearby radios automatically rebroadcast messages, extending your range across the search area.
Receive
Team members get updates even beyond direct radio contact. Everyone stays coordinated.
Messages can hop through multiple radios to reach distant team members
