On Line Brochure mentioned "Real time communication" and "High Speed networking (Cellular and WiFi)
Also some of the photos show a base loaded ~3' vertical antenna.

Anyone ever picked up a signal from one of these???

Per the vendors web site and spec sheets it appears they communicate via "Secure Iridium satellite communications".  So, probably not going to be anything that could be received unless you were line of sight to the craft.
