priseborough 9c5f564dc5 AP_NavEKF : Fixes bug in initial earth magnetic field states 
The calculation for these states was not being bias corrected
 2014-03-30 07:43:52 +11:00
priseborough e1819bb53a AP_NavEKF : Add initial parameter defaults for Copter, Rover and Plane 2014-03-29 14:06:43 +11:00
priseborough 55c60b8f07 AP_NavEKF : Reduce Magnetometer innovation consistency check threshold 2014-03-26 21:29:47 +11:00
priseborough 45b1a2fa46 AP_NavEKF : Reduce GPS position innovation consistency fail threshold 
This patch reduces the maximum acceptable GPS jump from approximately 16 to 8 metres
This will provide copters with more protection for close in loiter situations
 2014-03-26 21:29:45 +11:00
Andrew Tridgell bafc664750 AP_NavEKF: use APM_BUILD_TYPE() macro 2014-03-26 12:42:11 +11:00
Andrew Tridgell e3792f9b26 AP_NavEKF: added a mechanism for per-vehicle-type defaults in EKF 2014-03-26 12:30:17 +11:00
priseborough 17cdac7bc8 AP_NavEKF : Clean up angle and mag field initialisation 
This path reduces duplicated code, eliminates unused variables and
causes the earth magnetic field states to be reset when exiting static mode
which will occur every time copter is armed. This enables copters to be
powered on and initialised inside vehicles or houses, without bad earth
field values affecting flight.

Paul Riseborough d83b382e59 AP_NavEKF : Fix variance constraint bug 
Constraining variances to a minimum value of 1e-9 was causing problems
with gyro bias and angular accuracy in noisy GPS environments.
Because the constraint is applied after every covariance prediction
and correction, a lower value of 0 is more appropriate.
