Paul Riseborough 430d4b1cf8 EKF: ensure data in buffers is zero at startup 2016-04-05 22:23:37 +02:00
Paul Riseborough 470098e182 EKF: update default tuning parameters
Parameters needed to be changed when covariance prediction error was corrected.
The magnetic earth and body field process noise now use separate parameters to help with tuning

Paul Riseborough eaf94935f0 EKF: Fix bug in initialisation of height and magnetic field
This prevents zero data being used to form the initial height and magnetic field.
Do not start sampling initial values until non-zero time values are retrieved from the buffer.
