Step 1 AOI Define the mission footprint, demand density, and terrain source.

Area of interest (AOI)

Show AOI on map

Upload AOI file Draw AOI on map

Upload an AOI polygon KML or KMZ.

Restricted placement zones

Use these areas to prevent solver placement of repeater or extender candidates, such as flood zones, access-denied terrain, or UAS flight restrictions.

Upload one or more KML/KMZ polygon layers, or draw polygons on the map and save them as solver exclusion zones.

Reference layers

Bring in KML/KMZ overlays like fire lines, existing towers, TAK exports, or projected hazard footprints. These are informational for now, but they travel with the run outputs.

Reference layers render in Build mode and also show up in Results outputs so you can carry the same context forward.

Demand-point spacing

50 m | Area: ? | Est. points: ? | Compute: ?

Optimization target

Target coverage (%)

Set the desired covered-demand percentage here so the mission footprint and success target are defined together.

Step 2 Assets Define the deployable inventory available to the planner.

Deployable assets

Static and rotor assets are treated like point sites. Fixed-wing assets use the loiter radius conservatively for solve and backhaul logic, while default display heatmaps use a faster centerpoint preview unless you force the heatmap backend to match the solver.

Step 3 Anchors Add fixed sites and backhaul requirements.

Reference anchors

Advanced anchor RF/backhaul overrides

Backhaul planning

Plan backhaul links Require connected mesh Require gateway anchor

Max backhaul distance (km)

Backhaul confidence floor

Backhaul candidate pool (K)

Require Fresnel clearance

Backhaul frequency override (MHz)

Step 4 Priority Coverage Mark the critical locations that must receive service.

Priority coverage points

Priority coverage target (%)

Priority snap radius (m)

Constraint mode

Step 5 Advanced Settings Tune solver behavior, candidate generation, and heatmap export settings.

Protocol profile

Supported protocol

Supported fielded protocol profiles with approved planner defaults.

Reuse same protocol defaults for backhaul

Hide incompatible device presets in asset and anchor rows

Protocol RF overrides

Leave blank to use the selected protocol profile defaults. Receiver height is controlled separately under solver controls.

Center frequency (MHz)

Channel bandwidth (kHz)

RX threshold (dBm)

Required margin (dB)

RX antenna gain (dBi)

RX feed loss (dB)

Propagation model

Terrain/RF backend

This currently applies to both access coverage and backhaul evaluation so comparisons stay apples-to-apples.

Environmental penalties

Keep the terrain backbone separate from clutter and moisture. These controls stay source-agnostic so you can point them at open, commercial, or mounted local repos later without changing the mission shape.

Enable vegetation penalty

Vegetation mode

Enable structure penalty

Moisture state

Moisture stays deliberately conservative for now. It is useful for sensitivity testing, not yet a weather-realism claim.

Frontier pocket injection

Choose whether frontier pockets reorder existing candidates, inject new nearby candidates, or do both.

Pick offset

Heatmaps

Combined heatmap spacing (m)

Heatmap backend

Export per-site heatmaps

`Fast display` keeps recommendation and backhaul on the selected solver backend, but uses a quicker preview path for raster overlays. For fixed-wing assets that means a centerpoint display approximation instead of full loiter-ring evaluation. Choose `Match solver backend` when you want the slower strict view.

Scale preset

Confidence low

Confidence high

Margin low (dB)

Margin high (dB)

Red means weak. Yellow is the usable edge. Green means stronger confidence or more RF headroom.
