Hi,
I want to build my own autopilot for my RC boat. Because I don’t let it go on big lakes or something like that, but on ship canals, I need an GPS with a high accuracy.
I found the Venus GPS Modul http://www.sparkfun.com/commerce/produc … ts_id=9133. I didn’t find one with a higher accuracy. Is this GPS suitable for my plan?
I read that the GPS returns the coordinates in NMEA-0183 or SkyTraq Binary sentences. Which of both is the default return of the Modul? And my last question:
How can I communicate with the GPS. Is it enough to connect the TX and RX Pins with Software Serial or Hardware Serial pins of the Arduino, or do I need a converter or something like that?
Greetings Philipp
