gps altitude mathematical model
Hai
I am using a Fastrax GPs module for my Project and it is working ok for all horizontal position data .
When trying to decode the GGA string to decode the altitude from MSL it gives a variying value .Actually I am almost 5 meters above sealevel. But the unit is variably outputting values from -25 to 65 meters.
Any idea?
With regards
