Hi,

i've decoded some nmea lines delivered by the location manager where i
retrieved the longitude, latitude, altitude and others informations.
Then i compared theses informations with those stored in a Location
object that i got from a location listener. I found out that there is
a difference between the location.altitude and the nmea.altitude. The
difference is always about 50 m.

I think android corrects the latitude but I'm not sure. Is somebody
has more informations about that ?

I've also retrieved the HDOP, VDOP and PDOP from the nmea lines but i
don't know how to compare them with the accuracy since it is given in
meters.
Does somebody know how to convert DOPs to accuracy ?

Thanks in advance for your help.
