Geospatial User Group – Third Wednesdays

On Wed, June 17, don’t miss Steve Kipp of Gateway Geospatial Group (G3) present, “Schrödinger’s Intelligence: Number Stations” at GÜG (Geospatial Users Group).

A geolocation problem in disguise. Anonymous shortwave broadcasts of spoken digits have run for almost a century, and the signal blankets the planet, so attribution collapses entirely into coordinates. Knowing who runs through knowing where. This talk works on the geolocation stack: Time Difference of Arrival (TDoA) across distributed Software-Defined Radio (SDR) receivers, hyperbolic multilateration, and receiver geometry tight enough to matter. It closes on a recent station the press pinned to one country until the math put the transmitter somewhere else entirely.
