Andrew Tridgell fc0d703b9b Rover: much simpler SPEED_TURN_GAIN implementation 
as soon as we hit the SPEED_TURN_DIST we lower target speed to the
specified gain

Andrew Tridgell 69b5f352f6 Plane: prevent a bad glide slope when first entering auto 
we need to ensure that prev_WP_loc is not used as it could be
completely different from current_loc. As a precuation, this also sets
up next_WP_loc so that when the set_next_WP() is first called that
prev_WP_loc is set to current_loc

priseborough 5fe0d2c1b2 AP_NavEKF: Add protection for accel bias estimation errors 
Don't do bias estimation if tilted by more than 60 degrees to prevent scale
factor errors affecting result unnecessarily.
Prevent Kalman gain from having the wrong sign due to numerical errors
associated with small process noise values.
Allow smaller Z accel bias process noise values to be set

priseborough 3222e8f7cb AP_NavEKF: Default parameter adjustments 
Bring Plane glitch protection thresholds into alignment with copter and
rover
Slight increase in accelerometer bias process noise to prevent bias
estimate divergence into limits (Rover and Plane only as Copter does not
seem respond as well to this change)
effective increase in threshold on divergence test to allow increased
margin for bad GPS velocities

Andrew Tridgell 65fd25fb5a AP_InertialSensor: fixed example build 2014-05-18 08:08:19 +10:00
Arthur Benemann e1b7e53c04 Copter: only acceept Guided waypoints in Guided mode 
Fix #1068. When receiving guided waypoints do not change to GUIDED mode. This serves as a safety precaution for GCS, since they must switch to guided mode before sending the waypoints.

priseborough a19015ed61 AP_NavEKF: Scale divergence check with covariance 
This provides consistent behaviour for a range of gyro bias process
noise settings and automatically adjusts sensitivity as filter learns bias
 2014-05-16 21:24:25 +10:00
priseborough 0337d44b2e AP_NavEKF: Fix bug causing immediate clearing of diverged status on reset 2014-05-16 21:24:04 +10:00
priseborough d150904dc6 AP_NavEKF: Increase gyro bias process noise 
This is required to stop the bias estimate from becoming too static
towards the end of longer flights.

Randy Mackay 481a55867e Copter: only send sonar distance to GCS when sonar enabled 2014-05-16 14:46:56 +09:00
Ben Nizette 8c7b4feac1 Copter: send sonar distance to GCS via MAVLink 
At the moment, the copter sonar set up does not have access to the
raw sonar readings so this code sets the voltage field to zero.

Andrew Tridgell 49e7ee9ba7 GCS_MAVLink: added setup_uart() method 
this provides a common way of dealing with UART setup for a GCS
instance. It includes code to cope with SiK radios stuck in bootloader
mode.

Andrew Tridgell b3c1e515dc AP_AHRS: when no accel info available in buffer use current value 
this prevents an initialisation error, and is reasonable in flight too

priseborough f01cc78d37 DataFlash: Add EKF fault status logging 2014-05-15 21:14:21 +10:00
priseborough ce8e1daa16 AP_NavEKF: Improved divergence detection and reset 
Divergence is now detected by looking for very large changes in the gyro
bias. This will cause the filter to be reset and declared unhealthy for
10 seconds.

Don't reset filterDiverged status immediately during reset

Set filterDiverged true if covariance blows up

Add fault status reporting
