SignalPlanner

SignalPlanner brings professional-grade RF propagation modelling to iPhone and iPad. Plan repeater coverage, a backhaul link, or emergency-communications reach in the field or at your desk. PROPAGATION MODELS ITM Longley-Rice — terrain diffraction, with ground type and climate zone Hata Urban and Hata Rural — empirical loss for built-up and open ground COST-231 Urban — extended Hata above 1.5 GHz FSPL + Clutter — free-space loss plus land-cover attenuation Two-Ray + Clutter — ground reflection plus land-cover loss Strict LOS — line-of-sight only, for millimetre-wave paths Compare ITM with FSPL + Clutter on the same terrain, without replacing the saved map. TERRAIN AND LAND-COVER Elevation is NASA/USGS SRTM via AWS Mapzen Terrarium tiles (27 m), cached on device. Land-cover is ESA WorldCover 2021 at 10 m, with OpenStreetMap as fallback. Choose Coarse, Fine, or Very Fine (90 m). Cells grow coarser with range, out to 150 km. COVERAGE MAPS Set site, frequency, power, gain, and losses. Set the radius, or suggest it from the radio horizon. Strong and marginal zones use classic, rainbow, or colour-blind-safe colours. Carve a sector by azimuth and inner radius. Choose downlink, uplink, or two-way; two-way counts a spot only when both directions close. Tap for a link readout and S-meter. Styles: standard, satellite, hybrid, muted, or topographic. WEATHER Run the plan on a forecast: reliable, typical, and favourable coverage over 24, 48, or 72 hours, or any single hour. Ducting is flagged when it may stretch range. RELAYS, ROUTES, AND SITING Best Site ranks places for area, strong signal, or specific pins, and says when none covers them all. Repeater Chain finds the fewest hops between two sites. Repeater(s) reaches up to three far sites. Route coverage plans hops along a path. Band sweep compares frequencies from one site. POINT-TO-POINT AND ANTENNAS The link budget includes the terrain profile, Fresnel clearance, obstructions, fade margin, and a PDF. Import a measured pattern (MSI / Planet) so directional gain shapes the map and the link. HF AND SPACE WEATHER Solar indices, HF openings, and aurora / sporadic-E, saved for offline use. A skip-zone check, with NVIS notes, asks if two stations are too close for HF. The P.533 Full model (Experimental, not yet ITU-validated) estimates reliability, SNR, LUF, and multi-hop. MEASURED VS PREDICTED Import a CSV or JSON survey, or drop signal-report pins, and compare them with a map. You get an advisory offset. iOS cannot read live signal strength. MAP TOOLS Go to an address, lat/long, or MGRS. Drop a pin from GPS or with a long press. Measure distance, bearing, and area, and find high and low terrain. On supported devices, describe a plan in plain language and confirm it before it runs. OFFLINE AND EXPORT Cached terrain, weather, and space weather keep later runs offline. Share a PDF, or a KMZ of placemarks, rings, paths, routes, and a coverage overlay. PRESETS AND PRO Amateur, APRS, LMR, and data-link presets fill in frequency, sensitivity, and a model. Any frequency is still allowed. Four analyses are free. Map tools, KMZ, space weather, the skip-zone estimate, pattern import, link PDFs, and Measured vs Predicted stay free. Pro is a one-time purchase for unlimited runs: weather, Best Site, routes, repeaters, band sweep, and the HF Full model. PRIVACY No account. Location centres the map. Requests send only the coordinates being planned. No analytics, advertising, or tracking. Terrain: AWS Mapzen/Terrarium (MIT licence). Land-cover: ESA WorldCover 2021 (CC-BY 4.0). Topo: OpenTopoMap (CC-BY-SA 3.0). Streets: © OpenStreetMap contributors (ODbL). Elevation fallback: Open-Elevation (GPLv2). Weather: Open-Meteo. Space weather: HamQSL and NOAA SWPC. Predictions are estimates only. Do not rely on them alone for life-safety, mission-critical, or regulatory decisions. Always verify on site.
