I'm the author of the articles and did just now see the comments here. The brush contains a NFC tag and will open phillips.com once you hold it against your phone's NFC reader. That is the payload that comes back from this call.
You got a very noisy signal without much information (the gray thing in the background) with an random map overlay generated by wxtoimg. Try to hide the map overlay and you should see the picture you really received.
I already received aircraft positions (ADS-B), aircraft radio, ACARS, VDL, HFDL, satellite pictures, ISS pictures, a ISS astronaut speaking, a bunch of other satellites (including radio pirates on US military sats), small outdoor weather stations, a portable radio for children, some AM radio stations, a lot of ham radio and pagers.
There is also huge amount of signals I can't decode yet.
Many countries in these days try to build their own alternative to GPS, or in this example a extension for it. This for sure makes the location mor accurate and the systems are independant from the united states.
On the other hand for instance mobile phones have to implement all these systems and this makes them much more expensive and complicated. From my point of view it would be better to build up a universal international system. Yes, and I know this is nearly undoable.
