I was joking, Fred. I know about the limitations. Nes is right about the chipsets, except that anyone can buy them if you don't mind paying a premium with minimum quantities of 10,000. Of course, if you did that you would attract what might be described as scrutiny from people whose sense of humour has been surgically removed.

Domestic GPS chipsets use some assumptions about altitude to speed things up. If you invalidate those assumptions they will mostly work, but "mostly working" is not a phrase that pilots find reassuring.

And you should also be able to do the Kalman filtering in hardware on the module too...

And it needs its own GPS module to provide absolute frame of reference so it doesn't get confused by a coordinated turn.

If you can get it to work at 200 degrees and 50G accelerations we can build our own space probe. There may also be interest from small countries with hard to spell names run by alarming people.

(Forgive me but I've always wanted to say this)

You young whippersnappers don't know how good you've got it. The device you're fretting about is forty times faster than my first computer, on which the BASIC interpreter took 2000 microseconds to go round an empty loop. It has several hundred times more memory, uses about a fifth of the power and is about a tenth of the price.

When I was a lad we had to solder everything together ourselves. Some of the chips on my first motherboard were 74xx series discrete logic gates. Mass storage was done by bitbanging a modified cassette tape deck, and a full system reset typically involved a paperclip. 16K of RAM cost $30 at a time when you could buy a car for $3000 and it got static damaged just by thinking about touching it (or at least seemed to).

Every time I look at a Netduino I think about this and I'm amazed all over again.
