In short, yes, you do need to match the baud rate, data/stop bits, etc. exactly between GPS and Nios UART. You can do this in a couple of ways -- if you do not need to reconfigure the UART in operation (via software) I&#39;d recomend opening the Quartus project associated with your hardware design, launching SOPC Builder, and then editing the properties of the UART you&#39;re using.. you can change these settings, re-generate, re-compile, and then the UART should always operate at 4800 baud.

On a side note, this sounds interesting! I&#39;ve been wanting to do a project like this for some time but as usual, more important things get in the way of it...
