there is no algorithm to correct it as it is a dsp algorithm running inside the GPS.... what do you want to change.....

As i m currently using novatel gps receiver with comes with a software which output the lat,long,alittude data. i found out that there is a difference between nmea data and the software data given to me. so i was wondering how could i can correct the nmea (long,lat,alt) data to be close as maybe 50meters. thanks

Is it configured as SIRF protocol method.. check the default protocol and change it to nmea in the software.......
