I am currently looking for a low cost, I mean cheap, GPS solution for my Arduino Leonardo. What I need is a simple solution which offers me a high precision 1 pulse per second output of the GPS to my Arduino.
I borrowed 2 Adafruit GPS loggers. Unfortunately one seems to be broken, but the other works fine. But I don't need the sd card and the shield. I also couldn't find the accuracy of the 1pps (about 40 eur). The other thing I found is the xbee gps. It's cheaper and the data sheet states to have 30 ns acuracy of the 1pps. So it looks nice. (about 25 eur).
But what could you advice for me? It should be cheap and simple, so basically I don't need a shield as long as I can attach it by myself to the pins of my Arduino :).
Thank you in advance for telling me what you use,
