Peter Barker d8aa8d2b71 AP_NavEKF2: fix writeOptFlowMeas signature 
const some of the vectors, stop taking references to scalars that aren't
being changed

Randy Mackay 3d72022f6e EKF: modify ALT_SOURCE param description 
We regularly find users changing the ALT_SOURCE to 1 (range finder) when trying to implement terrain following which is not the correct way to do it

Peter Barker baa818a812 AP_NavEKF2: use compass singleton for logging 2018-07-04 20:11:27 +01:00
Peter Barker 578facc9ad AP_NavEKF2: do not pass GPS into Log_Write_GPS; it uses singleton 2018-04-18 13:50:55 +09:00

Peter Barker 3a99b2bce1 AP_NavEKF: move initialisation of EKF constants into header file 
Various comments where getting out of sync with one-another, and
having everything in one place lets you match values against types.

bugobliterator b1213a522d AP_NavEKF2: allocate NavEKF core from MEM_FAST region 2018-01-15 11:46:02 +11:00
Peter Barker 9c8466dc03 AP_NavEKF2: use GPS singleton 2017-12-27 00:58:02 +00:00
priseborough efdc651d1a AP_NavEKF2: Require reboot after changing ALT_SOURCE parameter 
Toggling between alt sources in flight using the parameter can have unpredictable effects due to the various height offsets and the possibility that the data source may be unavailable.

priseborough f2f3067326 AP_NavEKF2: Add interface to control GPS vertical velocity use 2017-08-10 19:49:45 +10:00
priseborough 027552ef44 AP_NavEKF2: Fix default behaviour for height origin corrections 
Previous default was to apply in-flight height origin changes to local position instead of to reported origin height. This caused problems with copters that took off before getting GPS lock.

Dr.-Ing. Amilcar Do Carmo Lucas 38b19b9eee AP_NavEKF2: Use SI units conventions in parameter units 
Follow the rules from:
http://physics.nist.gov/cuu/Units/units.html
http://physics.nist.gov/cuu/Units/outside.html
and
http://physics.nist.gov/cuu/Units/checklist.html
one further constrain is that only printable (7bit) ASCII characters are allowed

Dr.-Ing. Amilcar Do Carmo Lucas ce37517268 AP_NavEKF2: Improve comments, typos 2017-05-03 08:44:49 +09:00
Andrew Tridgell 2de8777669 AP_NavEKF2: added inter-EKF scheduling cooperation 
this changes the stragegy for load levelling between EKF cores so it
works between EK2 and EK3, and with future estimators as well.

It allows us to run EK3 and EK2 at the same time with good scheduling
performance

 2016-11-24 19:57:45 +09:00
priseborough e62863f9a1 AP_NavEKF2: Reduce unnecessary EKF core switching 
1) Do not switch to a core until its states have been updated.
2) Distinguish between mandated switches required for health failure and optional switches required due to innovation checks failing.
3) Apply hyseresis to innovation check levels
