The Deep Sweep

High-altitude Signal Intelligence

The Critical Engineering Working Group, 2015

deep sweep

Deep Sweep is an aerospace probe scanning the otherwise out-of-reach signal space between land and stratosphere, with special interest placed in the UAV/drone satellite communications routinely used in warfare and for surveillance of whole populations.

Taking the form of a high-altitude weather balloon, tiny embedded computer and RF equipment, The Deep Sweep project was developed to function as a low-cost, aerial signal-intelligence (SIGINT) platform. Intended for assembly and deployment by public, it enables surveying and studying the vast and often secretive world of signal in our skies.

Two launches have been performed so far, from sites in Germany, landing in Poland and Belarus respectively.
