Hi Paul,

we are using Novatel SMART V1G antenna (http://www.novatel.com/products/smartv1.htm) with OEMV-1G
receiver (http://www.novatel.com/Documents/Papers/OEMV1G.pdf), version GPS+GLONASS, 1Hz output.

We have choosen this model because it seems "better" (or at least higher priced...) than cheap GPS
modules. It is specified to have better accuracy and in fact it performs quite nice.

Hi Piotr,

What device are you using for global positioning?
