[FOSS-GPS] RTKLib processing power

[weber de souza calixto]

Hi,

Josh thanks for sharing your experience. Sure it is helping me a lot to
choose the processing platform. Right now I`m inclined to choose a
quad-core 1.2 Ghz A9 to start testing.

Danny, to use raspberry or beaglebone is dependant on your needs. In my
case I cant wait RTKLib to compute and then shoot the picture. Airplanes
can`t hover :)
