Situational Awareness Map STANDALONE

MIL-STD-2525 symbology, NATO affiliation filters, KML/KMZ overlays, offline tile caching, range rings, geofences, and bloodhound bearing lines.

🔔

Data Feeds FREE LIVE DATA

511 road incidents (ON, QC, BC, AB), Alert Ready emergency alerts, NRCAN wildfires, earthquakes, hurricanes, and severe weather — free, no subscription needed. ADS-B aircraft, AIS vessel tracking, weather radar, and traffic cameras require a Live Data subscription.

📊

Sensors & Vitals MESH SERVER

Barometer, magnetometer, and activity recognition broadcast in CoT. Auto-switch between vehicle and dismounted type. Per-vital sharing controls.

📹

Video Streaming TAK SERVER

Outbound RTMP streaming to all active TAK servers. Incoming RTSP video playback. Stream announcements visible to ATAK, WinTAK, and other TAK clients.

💬

Chat & Emergency MESH SERVER

Thread-based inbox with group channels and DMs. Emergency beacon with push notifications. Chat and emergency work over mesh — no server required.

📦

Export & Share STANDALONE

Export all CoT as JSON, TAK data package, KML tracks, CSV contacts, or chat log. Import CoT from JSON for offline device-to-device transfer via AirDrop.

Architecture & Communication Flow

TAK Can supports three simultaneous communication paths. Each device can use any combination depending on connectivity.

Mesh Networking — No Server Required

🔗

Auto-Discovery

Devices find each other automatically via WiFi and Bluetooth. No manual pairing, no configuration. Just enable mesh and go.

🔀

Multi-Hop Relay

Messages forward through intermediate devices with TTL-based loop prevention. Extend range beyond direct radio contact.

🌉

Bridge Mode

One device with internet bridges the entire mesh to the TAK server. Mesh-only devices see all server contacts. Only onboarded peers' data reaches the server.

🔐

PSK Encryption

Pre-shared key distributed via QR code. AES-GCM encryption on BLE mesh. HMAC-SHA256 authentication. Key rotation per mission.

Security at Every Layer

TAK Can is designed for sensitive operations. Security isn't an afterthought — it's built into every communication path.

Server connections TLS 1.2+ with client certificate authentication
MultipeerConnectivity DTLS encryption (Apple framework)
BLE mesh AES-GCM encryption with pre-shared key
Data at rest Core Data + log files encrypted via iOS file protection
Credentials Keychain with ThisDeviceOnly — no iCloud sync
Mesh bridge Only onboarded (server-authenticated) peers forwarded
BLE advertising Generic name — callsign not exposed over the air
