I believe they meant to say you get a 32-bit Arduino-compatible board for $19, and at "no extra charge" (eg. free, once you've bought the board) it has a GPS built into it to give you position and accurate time. Unlike any other Arduino-type board at that price that I'm aware of. The Arduino-compatible part of the codebase is also free as in libre (open source) although the GPS library is closed-source.

If anyone is interested in the GPS functions, I summarized the info spread out through the Indiegogo comments into an unofficial NavSpark FAQ here: http://pastebin.com/1f5iXwiT
If you just want the CPU by itself for general use and don't care about GPS, they are now offering 21 boards for $220 with just the CPU, regulator etc, no GPS so that would be $10.50 per board.
