Hi,
today we made our first flights only with the BMP085 pressure sensor.
We made an average of 4 pressure values and send the rate to 20 samples/s.
The altitude control system was stabile but just with an large error +7m -4m when flying ovals depending on the position.
After landing we had often a altitude of -1..-2m by a flight time of 30 minutes.
Has someone an idea to get more precise results?
Regards
Heinrich
