ARMING_CRSDP_IGN: Disable CrashDump Arming check

Note: This parameter is for advanced users

Must have value "1" if crashdump data is present on the system, or a prearm failure will be raised. Do not set this parameter unless the risks of doing so are fully understood. The presence of a crash dump means that the firmware currently installed has suffered a critical software failure which resulted in the autopilot immediately rebooting. The crashdump file gives diagnostic information which can help in finding the issue, please contact the ArduPIlot support team. If this crashdump data is present, the vehicle is likely unsafe to fly. Check the ArduPilot documentation for more details.

ARSPD Parameters

ARSPD_ENABLE: Airspeed Enable

Values
Value Meaning 0 Disable 1 Enable

ARSPD_TUBE_ORDER: Control pitot tube order

Note: This parameter is for advanced users

This parameter allows you to control whether the order in which the tubes are attached to your pitot tube matters. If you set this to 0 then the first (often the top) connector on the sensor needs to be the stagnation pressure (the pressure at the tip of the pitot tube). If set to 1 then the second (often the bottom) connector needs to be the stagnation pressure. If set to 2 (the default) then the airspeed driver will accept either order. The reason you may wish to specify the order is it will allow your airspeed sensor to detect if the aircraft is receiving excessive pressure on the static port compared to the stagnation port such as during a stall, which would otherwise be seen as a positive airspeed.

This determines when the filter will use the 3-axis magnetometer fusion model that estimates both earth and body fixed magnetic field states, when it will use a simpler magnetic heading fusion model that does not use magnetic field states and when it will use an alternative method of yaw determination to the magnetometer. The 3-axis magnetometer fusion is only suitable for use when the external magnetic field environment is stable. EK2_MAG_CAL = 0 uses heading fusion on ground, 3-axis fusion in-flight, and is the default setting for Plane users. EK2_MAG_CAL = 1 uses 3-axis fusion only when manoeuvring. EK2_MAG_CAL = 2 uses heading fusion at all times, is recommended if the external magnetic field is varying and is the default for rovers. EK2_MAG_CAL = 3 uses heading fusion on the ground and 3-axis fusion after the first in-air field and yaw reset has completed, and is the default for copters. EK2_MAG_CAL = 4 uses 3-axis fusion at all times. NOTE: The fusion mode can be forced to 2 for specific EKF cores using the EK2_MAG_MASK parameter. NOTE: limited operation without a magnetometer or any other yaw sensor is possible by setting all COMPASS_USE, COMPASS_USE2, COMPASS_USE3, etc parameters to 0 with COMPASS_ENABLE set to 1. If this is done, the EK2_GSF_RUN and EK2_GSF_USE masks must be set to the same as EK2_IMU_MASK.

Increment	Range
25	100 to 1000

EK3_GLITCH_RAD: GPS glitch radius gate size (m)

Note: This parameter is for advanced users

This controls the maximum radial uncertainty in position between the value predicted by the filter and the value measured by the GPS before the filter position and velocity states are reset to the GPS. Making this value larger allows the filter to ignore larger GPS glitches but also means that non-GPS errors such as IMU and compass can create a larger error in position before the filter is forced back to the GPS position. If EK3_GLITCH_RAD set to 0 the GPS innovations will be clipped instead of rejected if they exceed the gate size set by EK3_VEL_I_GATE and EK3_POS_I_GATE which can be useful if poor quality sensor data is causing GPS rejection and loss of navigation but does make the EKF more susceptible to GPS glitches. If setting EK3_GLITCH_RAD to 0 it is recommended to reduce EK3_VEL_I_GATE and EK3_POS_I_GATE to 300.

EK3_ALT_M_NSE: Altitude measurement noise (m)

Note: This parameter is for advanced users

This is the RMS value of noise in the altitude measurement.

A larger value for EK3_ALT_M_NSE may be required when operating with EK3_SRCx_POSZ = 0. This parameter also sets the noise for the 'synthetic' zero height measurement that is used when EK3_SRCx_POSZ = 0.

EK3_HGT_I_GATE: Height measurement gate size

Note: This parameter is for advanced users

This sets the percentage number of standard deviations applied to the height measurement innovation consistency check. Decreasing it makes it more likely that good measurements will be rejected.

If EK3_GLITCH_RAD set to 0 the vertical position innovations will be clipped instead of rejected if they exceed the gate size and a smaller value of EK3_HGT_I_GATE not exceeding 300 is recommended to limit the effect of height sensor transient errors.

Increment	Range

EK3_MAG_CAL: Magnetometer default fusion mode

Note: This parameter is for advanced users

Note: Reboot required after change

This determines when the filter will use the 3-axis magnetometer fusion model that estimates both earth and body fixed magnetic field states and when it will use a simpler magnetic heading fusion model that does not use magnetic field states. The 3-axis magnetometer fusion is only suitable for use when the external magnetic field environment is stable. EK3_MAG_CAL = 0 uses heading fusion on ground, 3-axis fusion in-flight, and is the default setting for Plane users. EK3_MAG_CAL = 1 uses 3-axis fusion only when manoeuvring. EK3_MAG_CAL = 2 uses heading fusion at all times, is recommended if the external magnetic field is varying and is the default for rovers. EK3_MAG_CAL = 3 uses heading fusion on the ground and 3-axis fusion after the first in-air field and yaw reset has completed, and is the default for copters. EK3_MAG_CAL = 4 uses 3-axis fusion at all times. EK3_MAG_CAL = 5 uses an external yaw sensor with simple heading fusion. NOTE : Use of simple heading magnetometer fusion makes vehicle compass calibration and alignment errors harder for the EKF to detect which reduces the sensitivity of the Copter EKF failsafe algorithm. NOTE: The fusion mode can be forced to 2 for specific EKF cores using the EK3_MAG_MASK parameter. EK3_MAG_CAL = 6 uses an external yaw sensor with fallback to compass when the external sensor is not available if we are flying. NOTE: The fusion mode can be forced to 2 for specific EKF cores using the EK3_MAG_MASK parameter. NOTE: limited operation without a magnetometer or any other yaw sensor is possible by setting all COMPASS_USE, COMPASS_USE2, COMPASS_USE3, etc parameters to 0 and setting COMPASS_ENABLE to 0. If this is done, the EK3_GSF_RUN and EK3_GSF_USE masks must be set to the same as EK3_IMU_MASK. A yaw angle derived from IMU and GPS velocity data using a Gaussian Sum Filter (GSF) will then be used to align the yaw when flight commences and there is sufficient movement.

EK3_BETA_MASK: Bitmask controlling sidelip angle fusion

Note: This parameter is for advanced users

Note: Reboot required after change

1 byte bitmap controlling use of sideslip angle fusion for estimation of non wind states during operation of 'fly forward' vehicle types such as fixed wing planes. By assuming that the angle of sideslip is small, the wind velocity state estimates are corrected whenever the EKF is not dead reckoning (e.g. has an independent velocity or position sensor such as GPS). This behaviour is on by default and cannot be disabled. When the EKF is dead reckoning, the wind states are used as a reference, enabling use of the small angle of sideslip assumption to correct non wind velocity states (eg attitude, velocity, position, etc) and improve navigation accuracy. This behaviour is on by default and cannot be disabled. The behaviour controlled by this parameter is the use of the small angle of sideslip assumption to correct non wind velocity states when the EKF is NOT dead reckoning. This is primarily of benefit to reduce the buildup of yaw angle errors during straight and level flight without a yaw sensor (e.g. magnetometer or dual antenna GPS yaw) provided aerobatic flight maneuvers with large sideslip angles are not performed. The 'always' option might be used where the yaw sensor is intentionally not fitted or disabled. The 'WhenNoYawSensor' option might be used if a yaw sensor is fitted, but protection against in-flight failure and continual rejection by the EKF is desired. For vehicles operated within visual range of the operator performing frequent turning maneuvers, setting this parameter is unnecessary.

EK3_OGN_HGT_MASK: Bitmask control of EKF reference height correction

Note: This parameter is for advanced users

Note: Reboot required after change

When a height sensor other than GPS is used as the primary height source by the EKF, the position of the zero height datum is defined by that sensor and its frame of reference. If a GPS height measurement is also available, then the height of the WGS-84 height datum used by the EKF can be corrected so that the height returned by the getLLH() function is compensated for primary height sensor drift and change in datum over time. The first two bit positions control when the height datum will be corrected. Correction is performed using a Bayes filter and only operates when GPS quality permits. The third bit position controls where the corrections to the GPS reference datum are applied. Corrections can be applied to the local vertical position or to the reported EKF origin height (default).

EK3_DRAG_BCOEF_X: Ballistic coefficient for X axis drag

Note: This parameter is for advanced users

Ratio of mass to drag coefficient measured along the X body axis. This parameter enables estimation of wind drift for vehicles with bluff bodies and without propulsion forces in the X and Y direction (eg multicopters). The drag produced by this effect scales with speed squared. Set to a postive value > 1.0 to enable. A starting value is the mass in Kg divided by the frontal area. The predicted drag from the rotors is specified separately by the EK3_DRAG_MCOEF parameter.

Range	Units
0.0 to 1000.0	kilograms per square meter

EK3_DRAG_BCOEF_Y: Ballistic coefficient for Y axis drag

Note: This parameter is for advanced users

Ratio of mass to drag coefficient measured along the Y body axis.

Increment	Range	Units
0.1	0.1 to 2.0	meters per square second

EK3_DRAG_MCOEF: Momentum coefficient for propeller drag

Note: This parameter is for advanced users

This parameter is used to predict the drag produced by the rotors when flying a multi-copter, enabling estimation of wind drift. The drag produced by this effect scales with speed not speed squared and is produced because some of the air velocity normal to the rotors axis of rotation is lost when passing through the rotor disc which changes the momentum of the airflow causing drag. For unducted rotors the effect is roughly proportional to the area of the propeller blades when viewed side on and changes with different propellers. It is higher for ducted rotors. For example if flying at 15 m/s at sea level conditions produces a rotor induced drag acceleration of 1.5 m/s/s, then EK3_DRAG_MCOEF would be set to 0.1 = (1.5/15.0). Set EK3_MCOEF to a postive value to enable wind estimation using this drag effect. To account for the drag produced by the body which scales with speed squared, see documentation for the EK3_DRAG_BCOEF_X and EK3_DRAG_BCOEF_Y parameters.

INS_HNTC2_ Parameters

INS_HNTC2_ENABLE: Harmonic Notch Filter enable

Note: This parameter is for advanced users

Harmonic Notch Filter enable

Values
Value Meaning 0 Disabled 1 Enabled

INS_HNTC2_FREQ: Harmonic Notch Filter base frequency

Note: This parameter is for advanced users

Harmonic Notch Filter base center frequency in Hz. This is the center frequency for static notches, the center frequency for Throttle based notches at the reference thrust value, and the minimum limit of center frequency variation for all other notch types. This should always be set lower than half the backend gyro rate (which is typically 1Khz).

Range	Units
10 to 495	hertz

INS_HNTC2_BW: Harmonic Notch Filter bandwidth

Note: This parameter is for advanced users

Harmonic Notch Filter bandwidth in Hz. This is typically set to half the base frequency. The ratio of base frequency to bandwidth determines the notch quality factor and is fixed across harmonics.

Range	Units
5 to 250	hertz

INS_HNTC2_ATT: Harmonic Notch Filter attenuation

Note: This parameter is for advanced users

Harmonic Notch Filter attenuation in dB. Values greater than 40dB will typically produce a hard notch rather than a modest attenuation of motor noise.

Range	Units
5 to 50	decibel

INS_HNTC2_HMNCS: Harmonic Notch Filter harmonics

Note: This parameter is for advanced users

Note: Reboot required after change

Bitmask of harmonic frequencies to apply Harmonic Notch Filter to. This option takes effect on the next reboot. A value of 0 disables this filter. The first harmonic refers to the base frequency.

INS_HNTC2_REF: Harmonic Notch Filter reference value

Note: This parameter is for advanced users

Note: Reboot required after change

A reference value of zero disables dynamic updates on the Harmonic Notch Filter and a positive value enables dynamic updates on the Harmonic Notch Filter. For throttle-based scaling, this parameter is the reference value associated with the specified frequency to facilitate frequency scaling of the Harmonic Notch Filter. For RPM and ESC telemetry based tracking, this parameter is set to 1 to enable the Harmonic Notch Filter using the RPM sensor or ESC telemetry set to measure rotor speed. The sensor data is converted to Hz automatically for use in the Harmonic Notch Filter. This reference value may also be used to scale the sensor data, if required. For example, rpm sensor data is required to measure heli motor RPM. Therefore the reference value can be used to scale the RPM sensor to the rotor RPM.

Range
0.0 to 1.0

INS_HNTC2_MODE: Harmonic Notch Filter dynamic frequency tracking mode

Note: This parameter is for advanced users

Harmonic Notch Filter dynamic frequency tracking mode. Dynamic updates can be throttle, RPM sensor, ESC telemetry or dynamic FFT based. Throttle-based harmonic notch cannot be used on fixed wing only planes. It can for Copters, QuaadPlane(while in VTOL modes), and Rovers.

Range	Values
0 to 5	Value Meaning 0 Fixed 1 Throttle 2 RPM Sensor 3 ESC Telemetry 4 Dynamic FFT 5 Second RPM Sensor

INS_HNTC2_OPTS: Harmonic Notch Filter options

Note: This parameter is for advanced users

Note: Reboot required after change

Harmonic Notch Filter options. Triple and double-notches can provide deeper attenuation across a wider bandwidth with reduced latency than single notches and are suitable for larger aircraft. Multi-Source attaches a harmonic notch to each detected noise frequency instead of simply being multiples of the base frequency, in the case of FFT it will attach notches to each of three detected noise peaks, in the case of ESC it will attach notches to each of four motor RPM values. Loop rate update changes the notch center frequency at the scheduler loop rate rather than at the default of 200Hz. If both double and triple notches are specified only double notches will take effect.

INS_HNTC2_FM_RAT: Throttle notch min freqency ratio

Note: This parameter is for advanced users

The minimum ratio below the configured frequency to take throttle based notch filters when flying at a throttle level below the reference throttle. Note that lower frequency notch filters will have more phase lag. If you want throttle based notch filtering to be effective at a throttle up to 30% below the configured notch frequency then set this parameter to 0.7. The default of 1.0 means the notch will not go below the frequency in the FREQ parameter.

Range
0.1 to 1.0

INS_HNTCH_ Parameters

INS_HNTCH_ENABLE: Harmonic Notch Filter enable

Note: This parameter is for advanced users

Harmonic Notch Filter enable

Values
Value Meaning 0 Disabled 1 Enabled

INS_HNTCH_FREQ: Harmonic Notch Filter base frequency

Note: This parameter is for advanced users

Harmonic Notch Filter base center frequency in Hz. This is the center frequency for static notches, the center frequency for Throttle based notches at the reference thrust value, and the minimum limit of center frequency variation for all other notch types. This should always be set lower than half the backend gyro rate (which is typically 1Khz).

Range	Units
10 to 495	hertz

INS_HNTCH_BW: Harmonic Notch Filter bandwidth

Note: This parameter is for advanced users

Harmonic Notch Filter bandwidth in Hz. This is typically set to half the base frequency. The ratio of base frequency to bandwidth determines the notch quality factor and is fixed across harmonics.

Range	Units
5 to 250	hertz

INS_HNTCH_ATT: Harmonic Notch Filter attenuation

Note: This parameter is for advanced users

Harmonic Notch Filter attenuation in dB. Values greater than 40dB will typically produce a hard notch rather than a modest attenuation of motor noise.

Range	Units
5 to 50	decibel

INS_HNTCH_HMNCS: Harmonic Notch Filter harmonics

Note: This parameter is for advanced users

Note: Reboot required after change

Bitmask of harmonic frequencies to apply Harmonic Notch Filter to. This option takes effect on the next reboot. A value of 0 disables this filter. The first harmonic refers to the base frequency.

INS_HNTCH_REF: Harmonic Notch Filter reference value

Note: This parameter is for advanced users

Note: Reboot required after change

A reference value of zero disables dynamic updates on the Harmonic Notch Filter and a positive value enables dynamic updates on the Harmonic Notch Filter. For throttle-based scaling, this parameter is the reference value associated with the specified frequency to facilitate frequency scaling of the Harmonic Notch Filter. For RPM and ESC telemetry based tracking, this parameter is set to 1 to enable the Harmonic Notch Filter using the RPM sensor or ESC telemetry set to measure rotor speed. The sensor data is converted to Hz automatically for use in the Harmonic Notch Filter. This reference value may also be used to scale the sensor data, if required. For example, rpm sensor data is required to measure heli motor RPM. Therefore the reference value can be used to scale the RPM sensor to the rotor RPM.

Range
0.0 to 1.0

INS_HNTCH_MODE: Harmonic Notch Filter dynamic frequency tracking mode

Note: This parameter is for advanced users

Harmonic Notch Filter dynamic frequency tracking mode. Dynamic updates can be throttle, RPM sensor, ESC telemetry or dynamic FFT based. Throttle-based harmonic notch cannot be used on fixed wing only planes. It can for Copters, QuaadPlane(while in VTOL modes), and Rovers.

Range	Values
0 to 5	Value Meaning 0 Fixed 1 Throttle 2 RPM Sensor 3 ESC Telemetry 4 Dynamic FFT 5 Second RPM Sensor

INS_HNTCH_OPTS: Harmonic Notch Filter options

Note: This parameter is for advanced users

Note: Reboot required after change

Harmonic Notch Filter options. Triple and double-notches can provide deeper attenuation across a wider bandwidth with reduced latency than single notches and are suitable for larger aircraft. Multi-Source attaches a harmonic notch to each detected noise frequency instead of simply being multiples of the base frequency, in the case of FFT it will attach notches to each of three detected noise peaks, in the case of ESC it will attach notches to each of four motor RPM values. Loop rate update changes the notch center frequency at the scheduler loop rate rather than at the default of 200Hz. If both double and triple notches are specified only double notches will take effect.

Note: This parameter is for advanced users

The minimum ratio below the configured frequency to take throttle based notch filters when flying at a throttle level below the reference throttle. Note that lower frequency notch filters will have more phase lag. If you want throttle based notch filtering to be effective at a throttle up to 30% below the configured notch frequency then set this parameter to 0.7. The default of 1.0 means the notch will not go below the frequency in the FREQ parameter.

Range
0.1 to 1.0

KDE_ Parameters

KDE_NPOLE: Number of motor poles

Sets the number of motor poles to calculate the correct RPM value

LOG Parameters

LOG_BACKEND_TYPE: AP_Logger Backend Storage type

Bitmap of what Logger backend types to enable. Block-based logging is available on SITL and boards with dataflash chips. Multiple backends can be selected.

Bitmask
Bit Meaning 0 File 1 MAVLink 2 Block

LOG_FILE_BUFSIZE: Maximum AP_Logger File and Block Backend buffer size (in kilobytes)

The File and Block backends use a buffer to store data before writing to the block device. Raising this value may reduce "gaps" in your SD card logging. This buffer size may be reduced depending on available memory. PixHawk requires at least 4 kilobytes. Maximum value available here is 64 kilobytes.

LOG_DISARMED: Enable logging while disarmed

If LOG_DISARMED is set to 1 then logging will be enabled at all times including when disarmed. Logging before arming can make for very large logfiles but can help a lot when tracking down startup issues and is necessary if logging of EKF replay data is selected via the LOG_REPLAY parameter. If LOG_DISARMED is set to 2, then logging will be enabled when disarmed, but not if a USB connection is detected. This can be used to prevent unwanted data logs being generated when the vehicle is connected via USB for log downloading or parameter changes. If LOG_DISARMED is set to 3 then logging will happen while disarmed, but if the vehicle never arms then the logs using the filesystem backend will be discarded on the next boot.

Values
Value Meaning 0 Disabled 1 Enabled 2 Disabled on USB connection 3 Discard log on reboot if never armed

LOG_REPLAY: Enable logging of information needed for Replay

If LOG_REPLAY is set to 1 then the EKF2 and EKF3 state estimators will log detailed information needed for diagnosing problems with the Kalman filter. LOG_DISARMED must be set to 1 or 2 or else the log will not contain the pre-flight data required for replay testing of the EKF's. It is suggested that you also raise LOG_FILE_BUFSIZE to give more buffer space for logging and use a high quality microSD card to ensure no sensor data is lost.

Values
Value Meaning 0 Disabled 1 Enabled

LOG_FILE_DSRMROT: Stop logging to current file on disarm

When set, the current log file is closed when the vehicle is disarmed. If LOG_DISARMED is set then a fresh log will be opened. Applies to the File and Block logging backends.

Values
Value Meaning 0 Disabled 1 Enabled

LOG_MAV_BUFSIZE: Maximum AP_Logger MAVLink Backend buffer size

Note: This parameter is for advanced users

Maximum amount of memory to allocate to AP_Logger-over-mavlink

Increment	Range	Units
0.1	0 to 1000	hertz

LOG_DARM_RATEMAX: Maximum logging rate when disarmed

This sets the maximum rate that streaming log messages will be logged to any backend when disarmed. A value of zero means that the normal backend rate limit is applied.

Increment	Range	Units
0.1	0 to 1000	hertz

LOG_MAX_FILES: Maximum number of log files

Note: This parameter is for advanced users

Note: Reboot required after change

This sets the maximum number of log file that will be written on dataflash or sd card before starting to rotate log number. Limit is capped at 500 logs.

SCR_THD_PRIORITY: Scripting thread priority

Note: This parameter is for advanced users

Note: Reboot required after change

This sets the priority of the scripting thread. This is normally set to a low priority to prevent scripts from interfering with other parts of the system. Advanced users can change this priority if scripting needs to be prioritised for realtime applications. WARNING: changing this parameter can impact the stability of your flight controller. The scipting thread priority in this parameter is chosen based on a set of system level priorities for other subsystems. It is strongly recommended that you use the lowest priority that is sufficient for your application. Note that all scripts run at the same priority, so if you raise this priority you must carefully audit all lua scripts for behaviour that does not interfere with the operation of the system.

SERVO_VOLZ_RANGE: Range of travel

Range to map between 1000 and 2000 PWM. Default value of 200 gives full +-100 deg range of extended position command. This results in 0.2 deg movement per US change in PWM. If the full range is not needed it can be reduced to increase resolution. 40 deg range gives 0.04 deg movement per US change in PWM, this is higher resolution than possible with the VOLZ protocol so further reduction in range will not improve resolution. Reduced range does allow PWMs outside the 1000 to 2000 range, with 40 deg range 750 PWM results in a angle of -30 deg, 2250 would be +30 deg. This is still limited by the 200 deg maximum range of the actuator.
