It's a shame XGPS160 nor Garmin Glo have no external antenna connector.

VBOX sport is really expensive just to measure the acceleration of my car

From XPGS160 and VBOX i assume the first has the higher accuracy?
Will be there some gps in the near future also with Galileo support?

Is there some android smartphone you could tell its gps has usable accuracy for this 0-100 0.1s measurement?
Thanks

Hello, if i would like to measure 0-100kmh acceleration with 1/10s accuracy, how much Hz GPS do i need?
Thanks
