BA 140 — Tactical Signals / IMEI Signals Intercept and Location

An airborne wideband Software Defined Radio that detects, demodulates, and geo-locates RF emissions from 100 MHz to 6 GHz — Wi-Fi, cellular, walkie-talkie, and dedicated radio. Triangulated bearings on a moving map; optional jamming over the full band.

Why airborne SIGINT

Cover jungles, mountains, and open coast in one pass.

A single airborne sortie sweeps the entire RF spectrum across terrain that would take weeks to cover from the ground. Detect, demodulate, decode, and geo-locate weak or distant signals — then triangulate from successive bearings to fix the emitter on a map.

When the waveform is known, BA 140 can listen in to voice and data traffic in real time, or selectively jam the source using waveform-matched jamming strategies. Adversaries, trafficking networks, and smugglers are exposed the moment they key a radio in view of the aircraft.
