Take a look at this:

The tiny chip that can replace GPS satellites | Mail Online

=DThink of the space this could save=D

More room for the tinnies

 

That's going to mess up my fascination with space time and having to update the time.

 

No clues to the price and commercial availability, then.

 

All sorts of things one would like to know, but won't be told, like how robust current models are (it's a rough life being an artillery shell) and what rate of drift the accelerometers have, translated into geographical terms related to time of flight etc. I guess it will be like GPS, mil use first and eventually commercialisation.

 

"Contains 3 gyroscopes" FFS. How?? This will no doubt start a new arms race.

 

I would imagine that they are super miniature, super accurate Piezo electric gyroscopes like thay put in those 10 quid toy helicopters.

 

I was wondering how the gyro was achieved ..

Vibrating structure gyroscope - Wikipedia, the free encyclopedia

 

Very nice but the sums made my brain hurt

 

I put it up because I, for one, had no idea there were these different miniaturisable ways of achieving the gyroscope effect. Amongst other things I suppose that as long as one could calibrate the start position this could be included in a pet's microchip instead of gps, to the benefit of owners whose pets go missing. Other more sinister applications as well of course.
