Paul Riseborough be04be9b43 AP_NavEKF: Fix bug preventing home position being set by copter 
The interface definition has been modified so that it returns true for a position obtained usin geither the normal inertial navigation calculation, or a raw GPS measurement.
This enables this function to be used to set a home position before flight.

Paul Riseborough b71b8f4bda AP_NavEKF: Always return a NED relative position if possible

Paul Riseborough 2c4572eb50 AP_NavEKF: Make ground effect variable names more descriptive 2015-05-01 16:37:29 +09:00
Paul Riseborough 3986851c51 AP_NavEKF: Prevent Z accel bias changing during ground effect takeoff 
The inconsistent baro data during ground effect takeoff combined with the larger variances in the Z accel bias state early in flight can cause unwanted changes in bias estimate and therefore changes in height estimation error.
This patch turns of the process noise and state updates for the Z accel bias state when takeoff in ground effect is expected.
 2015-05-01 16:37:28 +09:00
Paul Riseborough 2cba60c731 AP_NavEKF: Decouple takeoff ground effect compensation from arm transtion 
Thsi fixes a potential bug where the vehicle could land at a lower location without disarming and re-enter ground effect takeoff mode wiht a baro height floor above the current altitude, causing unpredictable height gain

Paul Riseborough 8dc6354a54 AP_NavEKF: Prevent touchdown baro errors tripping height innovation check 
Ground effect baro errors can cause a spike in height innovation on disarming if ground effect compensation was used during the landing. This causes a transient AHRS fault message if this innovation is outside the pre-arm check limits.
Resetting the vertical position state to the measured height after disarming prevents this.

This estimate is used to offset baro data if we need to switch across from range finder data due to sensor failure. The previous filter coefficients gave a 0.5 seconds time constant on the offset which was too susceptible to baro noise.

Niels Joubert a5beef00d1 GPS: Official Swift Binary Protocol GPS Driver v3 for Piksi GPS 
DRIVER FEATURES:
- All logic for RTK vs Normal now lives inside Piksi
- Supports observation uplink through telem radio
- Supports full SBP packet logging
- Reports high-rate green blinking to indicate RTK lock.
- Switchable to accept only Float or Integer RTK locks.

THIS REQUIRES PIKSI FIRMWARE v0.14 OR HIGHER
- Uses Piksi's new Pseudo-Absolute-Positioning mode
- Onboard Piksi must have Pseudo-Absolute mode enabled
- Ground Station Piksi must have a surveyed location in settings
- Ground Station Piksi must send its location to Onboard Piksi.

NEXT STEPS REQUIRED:
- EKF needs to take higher accuracy GPS into account
- EKF needs to take GPS RTK height into account
- GCS needs to support sending SBP observation packets
--- MAVProxy patch forthcoming

Lucas De Marchi b292873304 AP_InertialSensor: fix starvation in L3G4200D 
The main thread would always be blocked on the semaphore to read the
data from accelerometer and gyroscope. Especially if we have a slow
update of these values in _accumulate() due to the I2C transfer function
taking too much time: the timer thread would never give up the CPU,
causing starvation on the main thread.

This fixes the issue by reducing the critical region using a flip-buffer
so _accumulate() can work on its own copy of the data. Now that the
critical region is smaller, also avoid the semaphore and use a spinlock
instead.

Lucas De Marchi f049c8e4c5 AP_HAL_Linux: remove needless call to mlockall() 
All threads share the same address space and have the same pages locked
into memory so it's not necessary to call mlockall() for each of them.

Grepping /proc/<tid>/status gives the same VmLck for all of them, even
when only the main thread locks the memory:

    # for i in `seq 477 482`; do \
	name=$(cat /proc/$i/comm); \
	vm=$(cat /proc/$i/status |grep VmLck); \
        echo -e "$name\t$vm"; \
    done

Lucas De Marchi e3d78b8960 AP_HAL_Linux: fix passing callback to member function 
It's undefined behavior to pass the callback to pthread to a class

members.

This fixes the following warnings:

Lucas De Marchi 62c2f737d5 AP_HAL_Linux: fix setting RT priorities 
LinuxScheduler::init() was not really working as it should. This was the
result of "ps -Leo class,rtprio,wchan,comm | grep ArduCopter":

FF      12 futex_ ArduCopter.elf
FF      12 usleep ArduCopter.elf
FF      12 hrtime ArduCopter.elf
FF      12 poll_s ArduCopter.elf
FF      12 hrtime ArduCopter.elf
FF      12 hrtime ArduCopter.elf

As can be seen all the threads run with the same priority, the one of the main
thread. There were basically 2 mistakes:

	1) pthread_attr_setschedpolicy() needs to be called before
	   pthread_attr_setschedparam(). Otherwise the latter will just return
	   an error and not set the priority

	2) pthread_create() defaults to ignore the priority and inherit the
	   it from the parent thread. pthread_attr_setinheritsched() needs to
	   be called to change the behavior to PTHREAD_EXPLICIT_SCHED. See
	   pthread_attr_setinheritsched(3) for an example program to test the
	   behaviors.

Also, it's undefined behavior to call pthread_attr_init() several times on the
same pthread_attr_t. Although we could reutilize the same attribute without
calling  pthread_attr_init() again, lets refactor the code a little bit, so all
the pthread calls are in a single place. Then also call pthread_attr_destroy()
when we are done.
