Randy Mackay 3e130273a9 AP_AHRS: do not fallback to DCM if EKF can provide relative position 2017-06-14 09:12:20 +09:00
Matt 6354ca7096 AP_AHRS: Set the new gps_fusion notify flag
Uses EKF filter state to set the new gps_fusion notify flag. This allows
the GCS and notify devices to specifically be notified if the GPS is or
is not usable.

Andrew Tridgell e78f55ef9b AP_AHRS: change order of EK2/EK3 update
if EK3 is our primary estimator when we want to run the EK3 update
first, so it gets time priority for inter-EKF scheduling.

Andrew Tridgell 09c969477f AP_AHRS: fixed fallback to DCM for get_position
this fixes dead-reckoning on fixed wing on GPS loss, and fallback to

Andrew Tridgell c62fc336cb AP_AHRS: use current EKF2 IMU core in gyro estimate
The EKF2 implementation uses one IMU per EKF2 core. When reporting the
gyro estimate, accel_ef estimate and gyro bias estimate we need to use
the values associated with the current IMU index being used by the
current EKF2 core. Otherwise we will have an inconsistency between the
gyro estimate and attitude estimate

This affects all multi-IMU systems using EKF2

Andrew Tridgell bf1e0e1536 AP_AHRS: fixed EKF GPS arming check for fixed wing

we use the checks always when disarmed

Caio Marcelo de Oliveira Filho 9d2e3157fe AP_AHRS: add a runtime flag for always using EKF
The AHRS_EKF_USE_ALWAYS define is used to force EKF to be always
used. It is defined only for building ArduCopter. Change it to be a
runtime flag. Keep its default value still based on the original define,
once the Copter uses it the define will be removed.

The motivation is to move vehicle specifc code out of the general
libraries. This patch shouldn't change behavior.

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.

Gustavo Jose de Sousa 54d5277842 AP_AHRS: standardize inclusion of libaries headers
This commit changes the way libraries headers are included in source files:

 - If the header is in the same directory the source belongs to, so the
 notation '#include ""' is used with the path relative to the directory
 containing the source.

 - If the header is outside the directory containing the source, then we use
 the notation '#include <>' with the path relative to libraries folder.

Some of the advantages of such approach:

 - Only one search path for libraries headers.

 - OSs like Windows may have a better lookup time.
