Andrew Tridgell 4fdbbd8984 AP_NavEKF: added functions to see if a nav source is enabled 
this allows us to avoid initialising ring buffers when not needed
 2020-12-01 10:53:08 +11:00
Andrew Tridgell ab917ed92e AP_NavEKF: add more protections on ring buffer code

initialised
 2020-12-01 10:53:08 +11:00
Peter Barker fdbffd19c6 AP_NavEKF_Source: remove defaults for baro and compass 
This makes all our defaults "NONE", meaning that a user will not see a
prearm failure for any source other than those in the primary set when
using the default configuration.

Paul Riseborough 4a743a3827 AP_NavEKF: Remove unnecessary reset operations and class variables 
The setting of EKF state variances is only required when commencing or recommencing velocity fusion.
The function that resets the EKF and GSF class variables has been renamed to be more consistent with its function.

Andrew Tridgell f79907bd1e AP_NavEKF: fixed build with vector index checking 2019-10-01 15:39:03 +10:00
Andrew Tridgell 688b01c6c6 AP_NavEKF: added a common parent class for EKF2 and EKF3 core classes 
this provides a common location for static intermediate variables in
EK2 and EK3. This has a few benefits:

 - the compiler can determine the address of the frequently accessed
   variables at compile time, making them faster

 - by sharing between EK2 and EK3 we save a lot of memory if both EK2
   and EK3 are enabled

 - we can fill all these with NaN in SITL on every loop, which allows
   us to catch cases where the variables are ever re-used between
   loops, which guarantees we aren't mixing data between EKF lanes or
   between EK2 and EK3

priseborough 487bbc3ed2 AP_NavEKF: Fix reporting of position status 
Split publishing of local position into horiz and vert components with separate validity checks
Split status reporting into separate update and get functions and only update once after each loop update. This removes unnecessary re-calculation of the status logic and ensures all consumers get the same data (avoid possible race conditions).

dgrat 41661f815f AP_Math: Replace the pythagorous* functions with a variadic template 
The new function can deal with a variable number of function parameters.
Additionally, I renamed the functions to norm(), because this is the
standard name used in several other projects.

Lucas De Marchi 798b743660 AP_NavEKF: use MAX() instead of maxf() 2015-12-01 16:28:18 -02:00
Lucas De Marchi 2591261af6 Global: rename min and max macros to uppercase 
The problem with using min() and max() is that they conflict with some
C++ headers. Name the macros in uppercase instead. We may go case by
case later converting them to be typesafe.

Lucas De Marchi d00c8e3a34 AP_NavEKF: remove checks for HAL_BOARD_APM2 and HAL_BOARD_APM1 2015-11-04 12:14:12 +11:00
Paul Riseborough 9b37c29efa AP_NavEKF: Improve mag earth state reset accuracy 
This removes errors in the in-flight reset of the earth field states by:

1) Using a state vector and magnetometer measurement from the same time coordinate
2) Not using the AHRS trim offsets in the calculation
 2015-11-02 17:47:01 +09:00
Paul Riseborough 0dd5a7c4fa AP_NavEKF: Use correct blended delta time for all vel and pos integration 
dtIMUactual has been spit into a separate dtDelAng and dtDelVel and dtDelVel1 and dtDelVel2 delta time in recognition of the amount of timing jitter and different update rates for the IMU's
 2015-11-02 17:47:00 +09:00
Paul Riseborough 42214ec303 AP_NavEKF: Fix failure to start mag cal due to gyro noise 
Vibration in the 400Hz delta angles could cause the angular rate condition check for in-flight magnetic field alignment to fail.
The symptons were failure to start magnetic field learning as expected when EK2_MAG_CAL=3 was set.
The calculation of a delta rotation between consecutive magnetometer samples has been introduced instead of the most recent IMU delta angle as this is less affected by noise and give an upper bound on the angular error.
the check has been moved into the magnetometer fusion control function so that any reset will be performed using fresh magnetometer data
 2015-11-02 17:46:59 +09:00
Paul Riseborough 707089178f AP_NavEKF: Update default parameter values:

Paul Riseborough 69d4bd2481 AP_NavEKF: Protect against baro data errors in constant position mode 
Large baro data errors when flying without GPS could cause total failure of the EKF.
This patch provides protection against this happening in-flight but allows for large innovations during preflight alignment.
 2015-11-02 17:46:55 +09:00

Lucas De Marchi 831d8acca5 Remove use of PROGMEM 
Now variables don't have to be declared with PROGMEM anymore, so remove
them. This was automated with:

    git grep -l -z PROGMEM | xargs -0 sed -i 's/ PROGMEM / /g'
    git grep -l -z PROGMEM | xargs -0 sed -i 's/PROGMEM//g'

The 2 commands were done so we don't leave behind spurious spaces.

AVR-specific places were not changed.
