Define accurate. Most deliver 2.5-3.0 metre CEP numbers. And most of that comes from good antenna placement, and an effective antenna.

The NEO-M8N supports multiple constellations, GPS+SBAS, GLONASS and GALILEO

We need the gps to calculate the Bearing to the next waypoint at >30hz. Accuracy max 10m . The vehicle will navigate at speed  ~3 ms for long hours >12 hours. Since the vehicle will travel ~200km and bobbing a lot  we need the gps to be reliable. is  NEO-M8L a good choice?
