The tactical map that flies your drones — even when GPS is jammed.
Real 3D terrain, MGRS and every grid, offline maps, ArduPilot and PX4 drone control, patrols that alert you to people and vehicles, and an encrypted team network that works with TAK. On iPhone, iPad, Mac and Android.
Guard a site. Fly through the jamming.
Two new capabilities that used to need separate systems — now on the same map as your plans, your team and your cameras.
DEMO3:11Three drones. One perimeter. Nothing missed.
- Set up in six steps — draw the site or pick a shape; along the edge, the whole area, or watch points like gates.
- Alerts for people and vehicles with a picture, the time and the coordinates — and the nearest drone goes to look by itself.
- Batteries handled — a drone running low is relieved, and its part is covered meanwhile.
- Every detection kept with Go to and CSV export; send alerts to your team and ATAK if you choose.
DEMO3:32GPS jammed or spoofed? Keep flying.
- A digital INS learned from how your drone leans and flies — the app takes over the moment GPS goes, with an honest circle of where it is.
- Spoofing caught — jumps, impossible speeds and positions that disagree with the drone’s lean are rejected, and the drone is told to drop its GPS.
- Map match — the camera’s picture is found on the satellite map by itself and fixes the position.
- Link lost too? A helper on ArduPilot flies it home. After landing, its own flight log gives the exact track.

Plan on real terrain, fly and watch drones, coordinate your team and analyse the ground — online or completely offline.
Real 3D terrain
Turn the ground through 360°. Satellite, topo and street maps, or your own WMS and XYZ sources.
Every grid
MGRS, UTM, Lat/Lon, British and Indian grids, in WGS 84, ED50 and other datums. Convert whole lists.
Offline maps
Download an area before you go. Everything keeps working without a signal.
Line of sight & viewshed
See what can be seen from any position, slope angles, and the high and low ground of an area.
Drone control
A ground station for ArduPilot and PX4: missions with heights above the ground, surveys, search patterns, a practice drone.
Live video & AR
Drone and IP camera video beside the map, detection of people and vehicles, your markers in the picture.
Team network & TAK
Positions, markers, plans and chat, encrypted end to end — with a server or in Mesh mode, and with ATAK users.
Tactical graphics
MIL-STD-2525D symbols, range rings, control measures and operation plans; KML, KMZ and GPX.
Made for people who can’t afford to get lost.
Plan, brief and coordinate on real terrain
- MGRS everywhere, military symbols and control measures
- Line of sight and viewshed before you move
- Team positions and orders, encrypted, with TAK users on the same picture
Guard a site around the clock with drones
- Perimeter patrols shared between several drones
- Alerts for people and vehicles with pictures and coordinates
- Battery changes planned; every detection kept for the report
Search the ground faster and safer
- Search patterns flown by drones, heights above the ground
- Live video on the map: tap the picture to mark the spot
- Works offline in the mountains; share positions with your team
A ground station that fits in your pocket
- ArduPilot and PX4, listen-only by default, every move confirmed
- Missions checked for terrain, radio line of sight and battery
- Keep flying when GPS is jammed or spoofed
Know the ground before you walk it
- 3D terrain, slope angles and the high and low points
- Offline maps, GPS tracks, walk to any point
- Sun and moon times, distances and bearings

Speaks MAVLink like your autopilot does.
No proprietary radios or cloud: the app talks to your drone directly over Wi-Fi or a network link, listen-only until you take control.

Good to know
Which devices does it run on?
iPhone, iPad and Mac (one App Store purchase covers all three) and Android phones and tablets from Google Play.
Which drones can it fly?
Multirotors running ArduPilot (ArduCopter) or PX4, connected over Wi-Fi or a network link with MAVLink. Listening is the default: nothing is sent to a drone until you take control.
Does it work without internet?
Yes. Download the maps and elevation of an area before you go, and the map, terrain analysis, coordinates, drone control and the team network (on a local network or Mesh mode) keep working offline.
How does flying without GPS work?
A short learning flight teaches the app how your drone leans and flies. When GPS is jammed or lies, the app keeps flying it on that inertial estimate, shows a circle of where it is, and fixes it from landmarks or by matching the camera to the satellite map. Always fly within your local drone rules.
Can my team use it with ATAK?
Yes. ATAK, WinTAK and iTAK users appear on your map and you on theirs, with GeoChat; you choose what is shared.
Can I try drone features without a drone?
Yes. Practice drones fly inside the app like ArduPilot drones, with pretend intruders for patrols and pretend jamming for flying without GPS. Nothing is sent anywhere.
Take the whole picture with you.
