The EKF uses a range of techniques acquired from several years of experience including an original method to handle the delayed time horizon problem.
The EKF uses a range of techniques acquired from several years of experience including an original method to handle the delayed time horizon problem.
A list of references I have found useful has been included.
- The Matlab script used to derive the autocoded expressions in the EKF can be found here: https://github.com/PX4/ecl/blob/master/EKF/matlab/scripts/Inertial%20Nav%20EKF/GenerateNavFilterEquations.m
- The python script used to derive the autogenerated expressions in the EKF can be found here: https://github.com/PX4/ecl/blob/master/EKF/python/ekf_derivation/main.py
- A working Matlab model of the filter capable of replaying flight data can be found here: https://github.com/PX4/ecl/tree/master/EKF/matlab/EKF_replay

/*
Autocode for fusion of a magnetic declination estimate where the innovation is given by
innovation = atanf(magMeasEarthFrameEast/magMeasEarthFrameNorth) - declinationAngle;
magMeasEarthFrameEast and magMeasEarthFrameNorth are obtained by rotating the magnetometer measurements from body frame to earth frame.
declinationAngle is the estimated declination as that location
This fusion method is used to constrain the rotation of the earth field vector when there are no earth relative measurements
(e.g. using optical flow without GPS, or when the vehicle is stationary) to provide an absolute yaw reference. In this situation the presence of yaw gyro errors
can cause the magnetic declination of the earth field estimates to slowly rotate.
Divide by zero protection and protection against a badly conditioned covariance matrix must be included.

NOTES FOR FUSION OF MEASUREMENTS USING AUTOCODE FRAGMENTS
The auto-code for the fusion of the various measurements provides in most cases the observation Jacobian and Kalman gain matrix for that observation.
Where no Kalman gain is provided, it will need to be calculated using the usual K = P*transpose(H)/(H*P*transpose(H) + R) where:
K = Kalman Gain matrix
H = observation partial derivative matrix (observaton Jacobian)
R = observation variance
(H*P*transpose(H) + R) is the innovation variance (always a scalar)
When the observation is a vector, it is always assumed that the errors in the vectors are uncorelated to each other and the observations are fused
sequentially, so no matrix inversion is required.
It is important that maximum useage of the sparsity in the H matrix be taken advantage of. If a sparse math library is available it could be used,
otherwise the matrix operations should need unrolled with inclusion of conditional statements to improve efficiency. Examples of this technique can
be found in the existing att_pos_ekf_estimator library
NOTES FOR COVARIANCE PREDICTION
Only expression for the upper diagonal is provided. The values will need to be copied across to the lower diagnal elements assuming symmetry
Process noise for time invariant states, eg Gyro bias, has not been included in the auto-code. The process noise variance for these states will
need to be added in a separate operation.

/*
Observation jacobian for fusion of the horizontal components of magnetometer measurements.
innovation = atan2(magE/magN) - declination, where magN and magE are the North and East components obtained
by rotating the measured magnetometer readings from body into earth axes.
This method of fusion reduces roll and pitch errors due to external field disturbances and is suitable for initial alignment and ground / indoor use
Divide by zero protection hs been added
