GPS wrong

Hi, whenever I play back my log file on google earth the position is about 20 miles west of where I was actually flying? also sometimes in return to lauch and loiter it will sometimes shoot off in completely the wrong direction and altitude? is this a problem with the GPS?

    Tested again today the Latitude seems to be about right? but Longtitude off by 26 miles

  • By any chance are you using a DIY Drones MediaTek MTK3229 of an "older" vintage ... more than a year old? (I forgot when they upgraded the firmware -- Jan '11?) and have not updated its firmware to "1.6"?




    Are you using your own NMEA parser?
