priseborough b651eac48d AP_NavEKF: Apply timeout to terrain offset validity reporting 
The terrain offset solution status is usable for a short period of time without state updates so a timeout has been added which prevents the rapid changes in solution status due to short duration sensor read errors.

Andrew Tridgell 745b739ab7 AP_InertialSensor: make calibrated() function fast enough to call in flight 
this will be used in plane to make AHRS SYS_STATUS unhealthy if a user
tries to fly with EKF enabled without a full 3D accel cal.

Note that it doesn't rely on using AP_Param load() to detect that a
value has been set, as some users are first doing a 3D cal then later
doing a 1D cal. In that case load() was returning true and would give
a false positive

Andrew Tridgell ef55a3c6a6 AP_GPS: keep reporting GPS status messages when no GPS at 1Hz 
to ensure the GCS knows that we have lost the GPS we need to keep
reporting GPS_RAW_INT messages when the GPS disappears. Sending at 1Hz
should be sufficient

priseborough 3e3dd9d695 AP_NavEKF: Fix parenthesis error in EKF status reporting and clean up logic 
This fixes a bug which could have caused the realative position status to be incorrectly reported under some conditions and also caused a compiler warning message. the logic used to report the filter solution status has been broken down into smaller, easier to understand statements.
 2015-01-01 23:39:48 +11:00
priseborough c06f6e105e AP_NavEKF: Consistent initialisation of tuning parameters and variables 
Non user adjustable parameters are now declared as 'const' in the header.
The _ prefix has been removed from non user adjustable tuning parameters.
We use a function call rather than a constructor to initialise variables because it enables the filter to be re-started in flight if necessary.
For consistency some signed integer type declarations have been changed to unsigned where appropriate.

priseborough f1dfa282dc AP_NavEKF: Consolidate constant velocity mode decision logic 
The decision to switch to constant velocity mode during optical flow operation and te decision to switch back were previously being made in two different places in code. Both decisions are now made in the one place which makes the code easier to follow and maintain.

 2014-12-31 13:14:12 +09:00
priseborough 0a5de21dc7 AP_NavEKF: Fix bug in reporting of solution status 
Because synthetic  position measurements at 0,0 are fused during position hold mode, a position timeout cannot be used as the only means of detecting position solution status.

 2014-12-31 13:14:04 +09:00
priseborough 363c1e393d AP_NavEKF: Latch use of position hold mode for duration of flight 
Required to prevent acquisition of GPS mid flight causing unwanted change in position and velocity
A distinction has been mad between the arm and disarm transition and the decision to use position hold mode (formerly static mode)
 2014-12-31 13:14:02 +09:00
priseborough a0a6c0362f AP_NavEKF: Relax timeout check applied to optical flow data 
200 msec was too short and could lead to false positives. 5000 msec is the largest time we can go free inertial.

 2014-12-31 13:13:54 +09:00
priseborough b160f4c03b AP_NavEKF: Compensate optical flow fusion for GPS glitch recovery offset 2014-12-31 13:13:52 +09:00
priseborough e4c969084d AP_NavEKF: Improve behaviour recovering from a GPS timeout 
When regaining GPS after a timeout, an offset is applied when fusing  GPS velocity so that GPS velocity and position data as fused by the EKF is kinematically consistent.
This velocity offset is also accounted for when fusing air data so that wind estimates are not corrupted when the GPS position offset is being pulle back to zero.
The intended behaviour is that the EKF position will be pulled back to the GPS position at a rate of 5m/s for planes and 1 m/s for copters. This avoids large deviations in trajectory when GPS is regained.

priseborough a16253796f AP_NavEKF: Fix bug preventing the non-GPS mode being selected externally 
When on the ground it is likely the flow sensor will be returning  data that does not meet the minimum quality requirements selected.
The previous check was for the presence of valid data. This has been loosened to look for the presence of data.
When the vehicle becomes airborne, the quality of flow data normally improves as the image comes into focus.
 2014-12-31 13:13:42 +09:00
priseborough a42100e4c5 AP_NavEKF: Improved handling of no GPS

priseborough 685fa383e4 DataFlash: Log EKF solution status message 
This message is a bitmasked integer that will be used by control software to determine what data is available from the EKF and decide what control modes are available.
Duplicate static mode message removed. Static mode is now contained in the bitmasked solution status message
 2014-12-31 13:13:33 +09:00
priseborough 4eb19c2324 AP_NavEKF: Rationalise health status reporting 
1) Un-used public methods to report height and position drifting have been removed
2) A time-out has been added to the airspeed innovation consistency check so that if we are relying on airspeed to constrain velocity drift, a filter divergence or other fault that causes the airspeed to be continually rejected will trigger a change in health status.
3) A timeout of velocity, position or height measurements does not cause a filter fault to be reported. Timeouts can be due to sensor errors and do not necessarily indicate that the filter has failed.
4) Time-outs of various measurements are used to present a consolidated bitmask which inidicates which parts of the solution can be used, eg attitude, height, velocity, relative position, absolute position, etc.

priseborough f2c506339a AP_NavEKF: Reduce time required to recover from GPS timeouts 
The time required for GPS to be lost or rejected before vehicles with airspeed sensors either reset to GPS or invoke the zero side-slip assumption to constrain drift has been reduced from 15 to 10 seconds
A duplicate zeroing of the GPS position offset has been removed
If the vehicle is a non hovering vehicle (eg a plane) then the speed at which the GPS offset is pulled back to zero after a reset is increased from 1 to 3  m/s

This also improves recovery from bad inertial data for planes

The introduction of the height rate flare logic caused the demanded height rate to be zero except when a flare manouevre was being performed. This caused the plane to lag behind height changes if the D gain was non-zero, which caused it to fly high during landing approach.

priseborough 13df6fb1c9 AP_NavEKF : Reduce ripple in estimates that can cause copter motor 'pulsing' 
This patch reduces the level of 5Hz and 10Hz 'pulsing' heard in motors due to GPS and altimeter fusion which cause a small 5Hz and 10Hz ripple on the output under some conditions. Attitude, velocity and position state corrections from GPS, altimeter and magnetometer measurements are applied incrementally in the interval from receiving the measurement to the predicted time of receipt of the next measurement. Averaging of attitude state corrections is not performed during periods of rapid rotation.

Time stamps are now explicitly initialised to the current IMU time to avoid unwanted activation of timeout logic on filter start and the various calls to the hal.scheduler->millis() object have been consolidated.

Unused variables have been removed

priseborough dcb252cc05 AP_NavEKF : Fix bug in reset of position and velocity states 
If the inertial solution velocity or position needs to be reset to the GPS, the stored state history for the corresponding states should also be reset.
Otherwise the next GPS measurement will be compared to an invalid previous state and will be rejected.
The position state should be reset to a GPS position corrected for velocity and measurement latency. This will make a noticeable difference for high speed flight vehicles, eg 11m at 50m/s

priseborough 874d0780aa AP_NavEKF: Reduce vulnerability to ground fixed magnetic interference 
Re-initialisation of the magnetic field states and yaw angle is now only performed a maximum of two times after start-up.

Once when coming out of static modefor the first time (first arm event)
Again (for copter only) when the altitude gain above the arming altitude exceeds 1.5m

this prevents magnetic interference present at arming (eg arming on a metal roof)from corrupting the magnetic field states enough to cause bad heading errors and toilet bowling on copter

John Williams 0fe3959d7e AP_HAL_Linux: Add support for in-kernel SPI CS handling 
Add support for /dev/spidev<bus>.<cs> in-kernel SPI CS handling, and convert
existing SPI devices over.

 * Add a new member _subdev to the LinuxSPIDeviceDriver class, and initialiser
   in LinuxSPIDevice constructor.  Use subdev 0 for GPIO-managed CS
 * Extend the _cs_pin to signed 16 bits and define SPI_CS_KERNEL (-1) for
   kernel-managed CS
 * Move to per-device file descriptors (required for in-kernel CS)
 * Extend spidev filenames to include bus and subdevice numbers, possibly
   longer than 1 digit each
 * Allow support for platforms enumerating /dev/spidevNNN from non-zero bases
 * Convert existing users over to the new API
