Checking GPS Accuracy and Radio Blackout Risk Before a Drone Survey Flight

A drone survey crew checks the weather before every flight. Clear skies, low wind, good visibility, the usual go/no-go checklist. What that checklist almost never includes is whether the sun is currently degrading GPS accuracy or blacking out HF radio, and that gap is exactly how a perfectly clear-sky flight turns into a redo.

Both signals are public and free. The National Weather Service publishes ground forecasts and active alerts. NOAA's Space Weather Prediction Center publishes the Kp index and the same X-ray flux data used to classify radio blackout severity on its own published R-scale. The problem isn't access, it's that these live on two separate specialist government sites, and almost nobody running a survey crew or a storm-restoration truck is going to check both before every job.

field-operations-risk-briefing combines them into one briefing per location: the NWS forecast and active alerts, plus current Kp index, radio blackout severity, and the latitude where aurora is currently visible (a rough proxy for how much the ionosphere is disturbed at that latitude right now). Feed it a list of job sites and get back one record per site instead of two browser tabs per site.

This matters for two different crews in different ways. A drone or precision-ag survey team relies on RTK-GPS accuracy that degrades during a disturbed ionosphere, wasting a flight that looked clear on the ground. A utility storm-response crew relies on HF radio for coordination in areas without cell coverage, and a radio blackout during restoration work is its own kind of costly surprise.

It's billed per location briefed, and the space-weather portion is fetched once per run and shared across every location, so briefing 10 sites costs the same as briefing 1 for that part.

You can try a live briefing right now with no Apify account needed, or run it directly on Apify for your own locations and schedule.
