[Paparazzi-devel] Altitude estimation wiht BMP-sensor

[Prof. Dr.-Ing. Heinrich Warmers]

Hi,
we have same problems with the altitude estimation with the Bosch 
BMP-sensor in combination with the altitude filter:
The sensor signal gives a variance in altitude of up to +- 5m.
There is a delay of    2 to 3s of the sensor signal and the filter 
output so that the altitude feedback control systems becomes instable.
It looks like, that the altitude information from the GPS and the 
pressure sensor is mixed.

Regards
Heinrich
