Nucleus

A portable mesh radio with two parallel networks built for ATAK. High-speed WiFi mesh for full ATAK operations — voice, video, SA, chat — with a LoRa mesh running in parallel to extend your reach miles beyond WiFi range. No plugins required.

Nucleus

ATAK-ready mesh radio with WiFi mesh and LoRa CoT bridge

  • ATAK Integration
  • ATAK works natively over the WiFi mesh — SA, chat, pictures, routes, and data packages at full speed with no plugins
  • Built-in CoT bridge transparently forwards ATAK SA and chat over Meshtastic LoRa — no plugin needed on the phone, zero configuration
  • ATAK voice plugin works across the WiFi mesh — contact discovery, multi-channel support
  • Video streaming via OpenTAK ICU — when OpenTAKServer is installed, its built-in MediaMTX server distributes video to all ATAK clients
  • Optional OpenTAKServer runs directly on a Nucleus node — portable TAK server for field operations
  • Radios & Connectivity
  • 802.11s WiFi mesh — ~30 Mbps close range, 1–5 Mbps out to 1–3 miles with elevation and LoS. WPA3 encrypted.
  • Built-in Meshtastic LoRa radio (RAK4631) — ~6.8 kbps (Short/Fast), tested 8+ miles with LoS
  • LoRa mode switchable via web UI: CoT Bridge mode or BLE mode (Meshtastic phone app)
  • Both radios use mesh topology — data hops through every connected node to extend range, auto-rerouting around failures
  • WiFi Access Point (5.8 GHz) for device connectivity
  • Ethernet port (RJ45) for wired connections or internet gateway
  • Additional Services
  • Onboard OpenDHT server — video, voice, and text via Jami with no internet or central server
  • Reticulum transport for decentralized encrypted messaging (Sideband, MeshChat)
  • Tailscale VPN for secure remote access when internet is available
  • Internet gateway — plug any node into an internet source and share it across the mesh

ATAK Integration

📡

Native ATAK Over WiFi

ATAK discovers other devices and shares SA automatically over the WiFi mesh. Pictures, chat, routes, and data packages all transfer at full WiFi speed — the way ATAK was designed to work.

🔗

LoRa CoT Bridge

The Nucleus runs a CoT bridge daemon that intercepts ATAK multicast traffic on the local network and transparently forwards SA and chat as CoT packets over Meshtastic LoRa. Remote positions appear natively in ATAK — no plugin required on the phone. Rate-limited and loop-protected for reliable operation.

🎙️

Voice Over Mesh

The ATAK voice plugin works natively across the WiFi mesh. Voice traffic, contact discovery, and channel selection all work between nodes automatically — including multi-hop.

🎥

Video Streaming

When OpenTAKServer is installed, its built-in video server receives feeds from OpenTAK ICU and distributes them to all ATAK clients on the mesh. Stream camera feeds from the field to every connected device.

🖥️

Portable OpenTAKServer

OpenTAKServer installs and runs directly on a Nucleus node. Centralized SA, data packages, mission planning, and video feeds — all on a portable, battery-powered device. No cloud, no base station, no external infrastructure.

🔄

Bridge / BLE Mode Toggle

Switch the LoRa radio between CoT Bridge mode for ATAK, or release it for Bluetooth pairing as a standard Meshtastic radio. Toggle from the web dashboard.

Private Communications

📞

Encrypted Voice & Video

Encrypted voice and video calls over the mesh via Jami. No phone company, no cloud accounts, no internet required. Works between remote nodes over Tailscale too.

💬

Secure Messaging

Reticulum-based encrypted messaging across the mesh, VPN tunnels, or internet. End-to-end encrypted regardless of transport. Use Sideband or Columba from a phone, MeshChat from a PC.

📻

Long-Range Encrypted Text

Meshtastic LoRa — encrypted text and GPS over radio. Multi-mile range through terrain that blocks WiFi. No cell towers, no infrastructure. Web UI included — no phone app required.

🔗

Remote Encrypted Link

Tailscale connects remote nodes over the internet via WireGuard. All services — calls, messaging, everything — work transparently over the tunnel.

🛡️

Encrypted Mesh Transport

The WiFi mesh itself is WPA3 encrypted — traffic between nodes is protected before any app-level encryption. Self-healing topology that reroutes around failures automatically.

🔮

Coming: Sovereign Networking

Yggdrasil overlay network comes installed but is not yet preconfigured. The goal: zero-dependency encrypted networking with no accounts and no coordination server.

Platform Details

🌐

Internet Gateway

Plug any node into an internet connection (Ethernet, Starlink, cellular) and the entire mesh gets internet access. Combine with Tailscale or Reticulum for secure internet-bridged communications.

🖥️

Web Dashboard

Built-in web interface for monitoring mesh status, configuring node settings, toggling LoRa bridge mode, and scanning WiFi channels — accessible from any device connected to the node.

🔩

COTS Components

All off-the-shelf, user-replaceable parts with 3D-printed enclosures. No proprietary hardware — repair or modify with standard components.

🐧

Linux-Based & Extensible

Full Linux OS with a standard IP network. Add services, run scripts, or integrate with existing infrastructure using basic Linux knowledge.
