Hi, >> Why do you think that the _rounded_ baro altitude would be more >> accurate then the GPS height?! >vertically 30 or 100m is a lot.
30m is 100ft, which is as precise as the ATC can see you on the SSR radar if you have a transponder. That's it for airspace infringements. In competition however, the FAI-approved logger's data is more important and it might be a good idea to check how it is measured there. (I guess if it's based on GPS data then all receivers should show a similar error in the same time and location). > that they are only right 90% of the time, and that 10% they can be > out by 100s of feet - which is no where near as bad as I thought. I have XCSoar set to display GPS altitude at all times and I have never seen a difference of more than a 100 feet compared to the baro altimeter. Of course I do not stare at it all the time, but hey, if it's 10% I should have noticed already. And it is on one of the cheapest unbranded PNAs on the market. -- Michal ------------------------------------------------------------------------------ Beautiful is writing same markup.
