Provide an option to always do learning
Make field learning decision logic clearer
Change defaults so that plane learns when airborne
Change defaults so that Rover does not learn (large external magnetic interference)

Paul Riseborough 71c399674a AP_NavEKF2: Delay use of magnetic field states until off-ground 
Magnetic interference whilst on the ground can adversely affect filter states. This patch ensures that the simpler and more robust magnetic heading observation method is used until the vehicle has cleared the ground.

Paul Riseborough f63c32531c AP_InertialNav: Address peer review comments 
The decision to set the origin to zero has been moved out of the AHRS library and into the inertial nav library as this is consumer specific.
 2015-10-20 15:21:36 +11:00
Paul Riseborough 58d57994f4 AP_AHRS: Rectify coding errors found during peer review 
Fixes code that didn't take into account fall-through behaviour of C++ switch statements
Makes get_rigin furnction more generic allowing the consumer to decide what to do with an invalid origin
 2015-10-20 15:21:36 +11:00
Paul Riseborough 27393855f1 AP_NavEKF2: Change assumed gyro calibration accuracy 
If an external gyro calibration has been performed, we should assume that it has been done under static conditions
Otherwise it is pointless and we should allow the EKF to find its own gyro bias offsets.

Paul Riseborough 67a669fcdc AP_NavEKF2: Correct comments for height measurement 2015-10-20 15:21:36 +11:00

Paul Riseborough d3a6690e4f AP_NavEKF2: Fix bugs preventing use of optical flow navigation 2015-10-20 15:21:36 +11:00
Paul Riseborough 24c0309e85 AP_InertialNav: Enable flight using EKF2 
All EKF functions are accessed via the AHRS library enabling AHRS_EKF_TYPE to determine which EKF is being used by the control loops
 2015-10-20 15:21:36 +11:00
Paul Riseborough e65ae51564 AP_AHRS: Enable AP_InertialNav to access all EKF functions via AP_AHRS 
This patch adds additional methods to the the AHRS library so that the AP_InertialNav library dow nto have to access the EKF directly. This enables Copter to fly using the EKF nominated by AHRS_EKF_TYPE.
It will also pave the way to elimination of the AP_InertialNav library.

Paul Riseborough 52fd369b2f AP_NavEKF2: Add methods to output and calculate vertical position derivative 
This patch calculates a derivative of the vertical position (positive down).
The derivative is exposed via a public function.
