My most recent tests have been transmitting location from a beacon using one and seeking with a vehicle using another. I am getting within 3', but not always on the first try (sitting in one location, it may report a few locations all very close to each other).

just so this doesn't get lost:

arbarnhart: GlobalSat EM-406a is also SIRFstar III and readily available as a component (more $).

flokos: And why it is so cheap?

 

One more in case it isn't easy to get this from the shout stuff...

If you are sourcing a board ready component, the Global EM 406a is around $40 US in the US. It is based on the SIRF star III just like the Pharos GPS-500 that I have been getting for under half that including delivery. The GPS-500 comes in a plastic shell that is easy to pop open and with .01" edge traces that are easy to solder to but you obviously have no warranty then . I advise testing with the USB cable and a PC before cracking it open. The EM 406a will come ready to attach to some boards like the Ardupilot. Once they are hooked up, they are practically identical in operation and accuracy. At your price point, I think SIRF star III based modules are your best bet/ It's just a matter of paying more for one that is board ready or hacking a consumer package one.
