Barometric altitude sensor #13

Open GoogleCodeExporter opened 9 years ago

GoogleCodeExporter commented 9 years ago

Integrate a barometric altitude sensor to allow for much tighter altitude 
control.  This will be 
especially useful for:
 - automated landings
 - hovering helicopters and quadcopters
 - vertical hovering of fixed-wing planes
 - flying low around the SparkFun building next year

Support for the BMP085 barometer has been added. Integration into the IMU is 
still required.

It seems that in addition, a pressure sensor would be useful for an autonomous 
underwater vehicle. 
Sonar based depth is subject to error due to inversion layers, schools of 
baitfish etc. looking down, and wave/swell action looking up. Even pressure 
based depth is subject to wave/swell/tide errors. 
There are real challenges for such a vehicle as there is no GPS, and thus the 
current feedback loop will not work for gyro correction, even with a 
magnetometer.

baro. altitude is integrated with the IMU for testing (with AUAV3) in branch 
_UDB5_WJP. This could easily be ported to branch _mw4 for flight testing and 
eventual merge into 4_X
