The Deep Sweep
- grey-area 11y agoThe Deep Sweep is an aerospace probe scanning the otherwise out-of-reach signal space between land and stratosphere, with special interest placed in UAV/drone to satellite communication. Taking the form of a high-altitude weather balloon, tiny embedded computer and RF equipment, The Deep Sweep project is being 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.
- gcb0 11y agowhat is a signal space?
- grey-area 11y agoI'm not related to the project, but I think by signal space they mean simply an area which signals pass through (and hence can be collected in). By getting up high they can probably get access to a lot of signals which you wouldn't see at ground level.
- gcb0 11y agothat doesn't make much sense, you can get all frequencies anywhere... unless signals get trapped in that altitude somehow because of some magnetic field? then you would have a brand new "layer" for all the usual frequencies...?
- grey-area 11y agoSignals are not frequencies and have a finite power and often defined direction, so every signal is not detectable in every place, particularly at ground level. Anyway, it looked an interesting project. The text is probably not written in their first language (hence constructs like 'signal space').
