Field manual
Everything Tactical GPS does, chapter by chapter — from reading your first grid to enrolling with a TAK server. Short, practical, written for the field.
Getting Started
The map screen, its controls, the tab bar and how everything fits together.
Maps & Overlays
Apple, Google, Mapbox 3D, OSM, topo and USGS base maps, the overlay stack, image overlays, offline regions, presets and the grid.
Layers & iCloud Sharing
Organise items into layers, and share one live with a team over iCloud.
Coordinates & Position
MGRS, USNG, UTM, national grids and any EPSG system — datums, precision grids, north reference, search and the speedometer.
Pins & Shapes
Pins, labels, photos, routes, areas and freehand sketches, with NATO APP-6 symbols, attachments and geofences.
Items, Folders & Tags
The list behind the map: search, sort, nested folders, tags and batch editing.
Navigation & Directions
Compass and route navigation, generated directions, off-route alerts, arrival and background guidance.
Tracker
Record tracks with activities and laps, review sessions, and backtrack to your start.
Terrain Analysis
Viewshed, line of sight, slope, contours, spot elevation and sea depth — plus the AR view.
Field Tools
Range rings, measurement, angles, geotagged photos, position averaging and true-scale PDF map printing.
Weather & Sky
Forecasts at any map point, sunrise and sunset, BMNT/EENT twilight and moon phase.
Team — TAK Server
Enrollment, position sharing, pins and shapes, GeoChat, geofence alerts and data packages.
External GNSS & RTK
Bluetooth receivers, the satellite sky view, antenna height and NTRIP corrections.
Import, Export & Backup
Sixteen formats in, nine out, and one archive that moves the whole app to a new iPhone.
Apple Watch
Your grid, the bearing to your target, a one-button mark and track control on the wrist.
