Paul Riseborough 0ea55e25f9 Merge pull request #78 from PX4/pr-addGpsHgtOption
EKF: Add option to use GPS for height and improve height fall-back behaviour
2016-03-23 11:19:01 -07:00
Paul Riseborough 400a6e12ba EKF: Ensure all data in buffers is initialised
This is a defensive change to prevent introduction of NaN's into the filter if data is read from the incorrect place in the buffer.

Paul Riseborough 064a0e4dbc EKF: Don't use GPS to set position noise when not using GPS 2016-03-16 20:12:36 +11:00

Paul Riseborough 9f3b1351f7 EKF: Don't initialise velocity to GPS on initial alignment
For initial alignment the velocity and position should start at zero

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.

Paul Riseborough 49023f3d7e EKF: fix travis build error 2016-03-13 21:56:28 +11:00
Paul Riseborough 7677a162aa EKF: Don't start the output observer before the main filter has initialised
This prevents the possibility of output transients if alignment is delayed.

Paul Riseborough 26238bc2f5 EKF: Allow for change in position when defining the WGS-84 origin position
This allows GPS aiding to commence later in flight without step changes in local position output
2016-03-11 11:03:43 +11:00
Paul Riseborough e0fcce1463 EKF: Make position and velocity reset publish success
Some users of the position and velocity reset functions will need to know if the reset has been successful.

Paul Riseborough e9ccfdd484 EKF: Update derivation scripts and outputs
Work around limitation in Symbolic toolbox environment space by incrementally saving and clearing workspace
Remove vehicle vertical position from optical flow prediction equations (use range measurement instead) and regenerate auto-code
Remove legacy optical flow auto-code conversion method as it is not required now a work around for symbolic toolbox limitations has been developed
Fix out of date syntax

Paul Riseborough dd1d58bab5 EKF: Remove unnecessary matrix operations from optical flow fusion
The updated formulation means that H_LOS[][8] is always zero, so these operations are no longer required.
