 2016-05-27 14:00:50 +10:00
Paul Riseborough 98c0b74a71 EKF: Initialise height correctly when using external vision data 
If EV height selected ensure switch to correct height mode as soon as EV data is received
The 0 height datum is not at the initialisation position, so the height state needs to be reset to the measurement on startup

Paul Riseborough 90d65071c1 EKF: Add output predictor processing option 
Setting the velocity tracking tine constant to a negative number causes the output predictor to use a different method of correcting the velocity which provides a velocity output that is kinematically consistent with the position output.

This may improve height controller performance under some circumstances

waltjohnson a9ca8c294c Generalized isfinite() in similar form as done in ekf.cpp e3b9800cac/EKF/ekf.cpp (L45-L52) 2016-05-19 10:34:16 -06:00
waltjohnson 6eaa00e3f9 isfinite() is not part of the math class, rather the math.h header file. 2016-05-19 10:07:45 -06:00
