Estimate whether trees, rain, and local obstructions could hurt Starlink speed before ordering or moving the dish.
Formula
const obstruction = Math.min(100, Math.max(0, inputs.sky_obstruction_pct || 0)); const rain = Math.min(120, Math.max(0, inputs.heavy_rain_hours || 0)); const clearSpeed = Math.max(20, inputs.clear_sky_speed_mbps || 180); const outage = Math.max(0, inputs.current_outage_hours || 0); const video = Math.max(0, inputs.video_call_hours || 0); const obstructionLoss = obstruction * 0.16; const weatherLoss = rain * 0.045; const estimated_snr = Math.max(4, 24 - obstructionLoss - weatherLoss); const speedPenalty = Math.min(0.75, obstruction / 125 + rain / 240); const predicted_speed = Math.max(10, clearSpeed * (1 - speedPenalty)); const workWeight = Math.min(12, video / 20); const obstruction_risk = Math.min(100, obstruction * 0.75 + rain * 0.18); const install_viability_score = Math.max(0, Math.min(100, (estimated_snr / 24) * 100 + Math.min(15, outage * 1.5) - workWeight)); return { estimated_snr: Math.round(estimated_snr * 10) / 10, predicted_speed: Math.round(predicted_speed), obstruction_risk: Math.round(obstruction_risk), install_viability_score: Math.round(install_viability_score) };Sky Obstruction (%)

Use the result to compare providers, request quotes, or send the scenario to a specialist when the numbers matter.
Starlink Obstruction & Signal Quality Calculator estimates signal quality, predicted speed, obstruction risk, and install viability from sky obstruction, heavy rain, expected clear-sky speed, video-call workload, and current outage pain. Use it as a pre-order decision check, then verify address availability and installation guidance with Starlink. This page uses the verified Starlink tracked referral path after the obstruction pre-check; confirm availability and plan pricing with Starlink before buying.
Use this technology calculator to compare scenarios before committing money, time, or a provider conversation.
The estimate combines Sky Obstruction (%), Expected Clear-Sky Speed, Heavy Rain Hours per Month and returns Estimated SNR, Predicted Speed, Obstruction Risk.
If the result changes your decision, verify the current quote, rate, eligibility rule, or provider term before acting.
