It's not that they are menat to stay, but basically the world is
roughly and messily devided into

  navigation, which computes position on/in the GPS device, and tends to
  communicate in NMEA

  surveying/raw, which exports sometimes raw pseudoranges and carrier
  phase measurements, usually (always?) not in NMEA, for either
  postprocessing or real-time processing.  The best-known open-source
  project for this is http://www.rtklib.com/
