Paul Riseborough 74078cde94 EKF: reset state variance when performing a height reset
Set vertical position and velocity variances using known sensor error characteristics if we have reset the states to the sensor readings.

Paul Riseborough a352c2f4e3 EKF: Fix posix build error
Memset cannot be used on a class like this. Setting the time elements to zero achieves the desired result.

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.

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.
