 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.

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.

priseborough 5bd4ee9715 AP_NavEKF: Use compensation for baro delay in position hold mode 2014-12-31 13:13:58 +09:00
priseborough 4dc1ee2d66 AP_NavEKF: Rename static mode to avoid confusion with other non-GPS modes 
This renames static mode as posHoldMode to make it clearer what this and the other non-GPS modes do
 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 6eb533121c AP_NavEKF: Add static mode to solution status message 2014-12-31 13:13:48 +09:00

priseborough 3891dada78 AP_NavEKF: remove unnecessary function 2014-12-31 13:13:44 +09:00
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 
This patch enables indoor operation of the EKF by putting it into static mode if optical flow operation is not enabled and no GPS is available
 2014-12-31 13:13:40 +09:00

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.

Andrew Tridgell b9adc6e466 AP_InertialSensor: prefer sensors that have zero error counts 
if a sensor has failed in flight then try not to use it if another
error-free sensor is available

Randy Mackay 4a1ba9b186 AC_WPNav: minor const fix 2014-12-27 13:19:32 +09:00

already provided so in keeping with our desire to keep things simple we
can remove this class

Randy Mackay d67b4a8d49 Notify: add pre_arm_gps_check flag 
RGB LED will remain flashing blue when vehicle is disarmed and this

 2014-12-26 12:32:34 +09:00
Andrew Tridgell c93ae67541 DataFlash: don't try and open logfile on failure more than once 
this prevents a corrupted microSD card from causing a continuous
attempt to open a log file while in flight, which can cause large
scheduler delays

Andrew Tridgell abd1ece6e3 DataFlash: don't write out parameters if log open fails 2014-12-21 14:50:42 +11:00
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

Readibility improvement
 2014-12-18 17:29:50 +11:00
priseborough f6ce25df2a AP_NavEKF: Do not reset vertical velocity state from GPS 
Doing this can cause large height and height rate errors if large GPS velocity errors cause the GPS tn be rejected for long enough to cause a timeout and reset of states.

priseborough e2d47f836e AP_TECS: Fix bug causing plane to fly high on landing approach 
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 c8fb376cc4 AP_NavEKF: Fix bug in bias rate of change limiting 
This doesn't change the behaviour, but means the result is achieved using the correct parameters, and comments are consistent

priseborough 5532750a99 AP_AHRS: Add public method to inhibit GPS useage when using EKF 
This provides the calling vehicle software the abiity to request the EKF to not use GPS.
An integer is returned that indicates the type of operation available:
0 = request rejected (request will only be accepted if the EKF is in static mode, eg pre-armed)
1 = request accepted, attitude, vertical velocity and position estimates available
2 = request accepted, attitude, height rate, height, horizontal velocity and relative position estimates available

priseborough 2dff76394d AC_PosControl: Add spike and noise filter to demanded angles 
This has been done to provide a smooth psotion hold when using an optical flow aided EKF which can be noisy.

priseborough 1f78a73cdb AP_NavEKF: Make flow measurement delay vehicle specific 
This takes into account the inter-sampling delay between the flow driver and the APM software which depends on the rate at which the dirver is being checked. This is 50Hz for plane and rover, and 200Hz for Copter.
