NMEA sentences do contain WGS84 coordinates, probably just not in the
appropriate format you need. Just convert the text to floats. Here is a
python snipplet:
"quad" is either N,S,E or W
def format_coords(coord, quad):
sign = 1
if quad == "S" or quad == "W":
sign = -1
if coord[4] == ".":
return (float(coord[0:2])+ float(coord[2:]) / 60.) * sign
elif coord[5] == ".":
return (float(coord[0:3]) + float(coord[3:]) / 60.) * sign
