Paul Riseborough 63b0cf4360 EKF: Fix baro height offset bug 2016-03-14 15:51:15 +11:00
Paul Riseborough 4bd79c9e5d Merge pull request #76 from PX4/pr-fixRngHgtMode 
EKF: Fix bugs preventing use of range finder as primary height source

Flight testing completed and I have checked that the other pending PR #75 rebases cleanly on it.
