Red Grid Link

ATAK alternative: encrypted Bluetooth team GPS tracker for SAR & hunting

Features & Capabilities

Your team. Your grid. No cell towers required.

Inspired by military blue force tracking systems like ATAK, Red Grid Link brings encrypted team coordination to civilian and professional teams -- without cell towers, accounts, or servers. Track your team's positions in real time over Bluetooth, navigate with military-grade MGRS precision, and operate completely offline.

Red Grid Link is an offline-first, MGRS-native coordination platform for small teams (2-8 people) operating beyond reliable cell service. It combines precision land navigation with Field Link -- zero-config proximity sync over Bluetooth (iOS Multipeer / Android Nearby). Lightweight where ATAK is complex. Cross-platform where ATAK is Android-only. Zero infrastructure where ATAK requires TAK Server.

FIELD LINK -- TEAM SYNC WITHOUT INFRASTRUCTURE:
Field Link is what sets Red Grid Link apart. Devices within proximity automatically discover each other and share encrypted position and marker data -- no internet, no configuration, no pairing codes. Just turn it on and your team appears on the map.
- BLE proximity (iOS Multipeer/Android Nearby) transport (cross-platform)
- AES-256-GCM encrypted sync with ECDH ephemeral session keys
- Compact delta payloads (under 200 bytes per position update)
- Tiered session security: Open (auto-join), PIN (4-digit), or QR code
- Ghost markers: see last-known positions when teammates move out of range
- Time-decay visualization: full opacity fades to outline over 30 minutes
- Velocity vectors project teammate movement direction at disconnect
- Snap-to-live animation on reconnect
- Expedition Mode: under 3% battery per hour (BLE-only, 30-second updates)
- Ultra Expedition Mode: under 2% battery per hour (BLE-only, 60-second updates)
- Auto-reconnect with exponential backoff on disconnect

MGRS-NATIVE NAVIGATION:
Built on the proven MGRS engine from Red Grid MGRS -- the same coordinate system used by NATO forces worldwide.
- Live MGRS coordinates (4/6/8/10-digit precision)
- MGRS grid overlay on offline maps (GZD to 100m resolution)
- Bearing, distance, and dead reckoning tools
- Magnetic declination (WMM model)
- NATO phonetic voice readout for hands-free grid calls

11 TACTICAL TOOLS:
- Dead Reckoning plotter
- Two-point Resection
- Pace Count tracker
- Bearing calculator with back azimuth
- Coordinate Converter (MGRS, lat/lon, DMS, UTM)
- Range Estimation (mil-relation formula)
- Slope Calculator (percentage and angle)
- ETA / Speed Calculator
- Magnetic Declination converter
- Celestial Navigation (sun/moon bearing reference)
- MGRS Precision Reference

OFFLINE MAP SYSTEM:
- Downloadable map packs from USGS Topo and OpenTopoMap
- Full offline operation -- maps cached locally as MBTiles
- MGRS grid lines rendered as a dynamic overlay at all zoom levels

4 OPERATIONAL MODES:
One engine, four presentation layers. Terminology, icons, and quick actions adapt to your mission:
- Search & Rescue -- sector assignments, clue markers, search patterns
- Backcountry -- camp, waypoint, and trail navigation
- Hunting -- stand locations, game sightings, property boundaries
- Training -- exercise objectives, rally points, phase lines

AFTER-ACTION REPORTS:
One-tap PDF export containing map snapshot, mission timeline, track data, timestamps, team roster, markers, and session log.

4 TACTICAL DISPLAY THEMES:
- Red Light: preserve night-adapted vision (free)
- NVG Green: night observation device compatibility (Pro)
- Day White: high-contrast for daylight (Pro)
- Blue Force: tactical blue display (Pro)
