Sensor options:

• Current preferred sensor is the BMP085 which can be obtained mounted from http://www.quadroufo.com/ This supersedes the original SMD500 also from Bosch.

Setup:

• Current recommended settings using UAVPSet are TEMP=0, P=4, D=4

Current performance:

• The BMP085 performance is approx +/- 3ft.
• The original SMD500 performance is +/- 10ft.

Current algorithm / future improvements:

• The BMP085 or SMD500 are automatically detected by the "gke" extensions to UAVP.
• The better performance of the BMP085 is mainly due to faster updates and associated averaging over several readings.
• Temperature compensation is not currently used in UAVX as it was found to introduce some noise at the relatively high sampling rates used. This may be reviewed later.
