Altitude from GPS

Hi all,I thought that you can get altitude data from gps - but looking over documentation (NMEA sentence data) for EM-406A SiRF III , I can't find any reference to it. Am I mistaken or just blind?Thanks

  • Thanks Peter! (I am not sure how I missed that.....)
  • Try the $GPGGA sentence that has the MSL altitude in metres.
    regards Peter
