AFS_AMSL_LIMIT: AMSL limit

Note: This parameter is for advanced users

This sets the AMSL (above mean sea level) altitude limit. If the pressure altitude determined by QNH exceeds this limit then flight termination will be forced. Note that this limit is in meters, whereas pressure altitude limits are often quoted in feet. A value of zero disables the pressure altitude limit.

Units

meters

AFS_AMSL_ERR_GPS: Error margin for GPS based AMSL limit

Note: This parameter is for advanced users

This sets margin for error in GPS derived altitude limit. This error margin is only used if the barometer has failed. If the barometer fails then the GPS will be used to enforce the AMSL_LIMIT, but this margin will be subtracted from the AMSL_LIMIT first, to ensure that even with the given amount of GPS altitude error the pressure altitude is not breached. OBC users should set this to comply with their D2 safety case. A value of -1 will mean that barometer failure will lead to immediate termination.

Units

AFS_RC: Enable RC Advanced Failsafe

Note: This parameter is for advanced users

This enables the RC part of the AFS. Will only be in effect if AFS_ENABLE is also 1

AFS_RC_MAN_ONLY: Enable RC Termination only in manual control modes

Note: This parameter is for advanced users

If this parameter is set to 1, then an RC loss will only cause the plane to terminate in manual control modes. If it is 0, then the plane will terminate in any flight mode.

AFS_DUAL_LOSS: Enable dual loss terminate due to failure of both GCS and GPS simultaneously

Note: This parameter is for advanced users

This enables the dual loss termination part of the AFS system. If this parameter is 1 and both GPS and the ground control station fail simultaneously, this will be considered a "dual loss" and cause termination.

AFS_RC_FAIL_TIME: RC failure time

Note: This parameter is for advanced users

This is the time in seconds in manual mode that failsafe termination will activate if RC input is lost. For the OBC rules this should be (1.5). Use 0 to disable.

AHRS_ORIENTATION: Board Orientation

Note: This parameter is for advanced users

Overall board orientation relative to the standard orientation for the board type. This rotates the IMU and compass readings to allow the board to be oriented in your vehicle at any 90 or 45 degree angle. The label for each option is specified in the order of rotations for that orientation. This option takes affect on next boot. After changing you will need to re-level your vehicle. Firmware versions 4.2 and prior can use a CUSTOM (100) rotation to set the AHRS_CUSTOM_ROLL/PIT/YAW angles for AHRS orientation. Later versions provide two general custom rotations which can be used, Custom 1 and Custom 2, with CUST_ROT1_ROLL/PIT/YAW or CUST_ROT2_ROLL/PIT/YAW angles.

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 limits the amplitude of high frequency oscillations caused by an excessive gain. The limit should be set to no more than 25% of the actuators maximum slew rate to allow for load effects. Note: The gain will not be reduced to less than 10% of the nominal value. A value of zero will disable this feature.

BRD_SER1_RTSCTS: Serial 1 flow control

Note: This parameter is for advanced users
Note: Reboot required after change

Enable flow control on serial 1 (telemetry 1). You must have the RTS and CTS pins connected to your radio. The standard DF13 6 pin connector for a 3DR radio does have those pins connected. If this is set to 2 then flow control will be auto-detected by checking for the output buffer filling on startup. Note that the PX4v1 does not have hardware flow control pins on this port, so you should leave this disabled.

COMPASS_ORIENT: Compass orientation

Note: This parameter is for advanced users

The orientation of the first external compass relative to the vehicle frame. This value will be ignored unless this compass is set as an external compass. When set correctly in the northern hemisphere, pointing the nose and right side down should increase the MagX and MagY values respectively. Rolling the vehicle upside down should decrease the MagZ value. For southern hemisphere, switch increase and decrease. NOTE: For internal compasses, AHRS_ORIENT is used. The label for each option is specified in the order of rotations for that orientation. Firmware versions 4.2 and prior can use a CUSTOM (100) rotation to set the COMPASS_CUS_ROLL/PIT/YAW angles for Compass orientation. Later versions provide two general custom rotations which can be used, Custom 1 and Custom 2, with CUST_1_ROLL/PIT/YAW or CUST_2_ROLL/PIT/YAW angles.

COMPASS_ORIENT2: Compass2 orientation

Note: This parameter is for advanced users

The orientation of a second external compass relative to the vehicle frame. This value will be ignored unless this compass is set as an external compass. When set correctly in the northern hemisphere, pointing the nose and right side down should increase the MagX and MagY values respectively. Rolling the vehicle upside down should decrease the MagZ value. For southern hemisphere, switch increase and decrease. NOTE: For internal compasses, AHRS_ORIENT is used. The label for each option is specified in the order of rotations for that orientation. Firmware versions 4.2 and prior can use a CUSTOM (100) rotation to set the COMPASS_CUS_ROLL/PIT/YAW angles for Compass orientation. Later versions provide two general custom rotations which can be used, Custom 1 and Custom 2, with CUST_1_ROLL/PIT/YAW or CUST_2_ROLL/PIT/YAW angles.

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).

The 3-axis magnetometer fusion is only suitable for use when the external magnetic field environment is stable.

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.

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_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.

Setting this to 1 will always target the highest energy peak. Setting this to 2 will target the highest energy peak that is lower in frequency than the highest energy peak. Setting this to 3 will target the highest energy peak that is higher in frequency than the highest energy peak. Setting this to 4 will target the highest energy peak on the roll axis only and only the roll frequency will be used (some vehicles have a much more pronounced peak on roll). Setting this to 5 will target the highest energy peak on the pitch axis only and only the pitch frequency will be used (some vehicles have a much more pronounced peak on roll).

FFT_NUM_FRAMES: FFT output frames to retain and average

Note: This parameter is for advanced users
Note: Reboot required after change

Number of output frequency frames to retain and average in order to calculate final frequencies. Averaging output frames can drastically reduce noise and jitter at the cost of latency as long as the input is stable. The default is to perform no averaging. For rapidly changing frequencies (e.g. smaller aircraft) fewer frames should be averaged.

Adjusts the engine's percentage of torque rise on autothrottle during ramp-up to governor speed. The torque rise will determine how fast the rotor speed will ramp up when rotor speed reaches 50% of the rotor RPM setting. The sequence of events engaging the governor is as follows: Throttle ramp time will engage the clutch and start the main rotor turning. The collective should be at flat pitch and the throttle curve set to provide at least 50% of normal RPM at flat pitch. The autothrottle torque limiter will automatically activate and start accelerating the main rotor. If the autothrottle consistently fails to accelerate the main rotor during ramp-in due to engine tune or other factors, then increase the torque limiter setting.

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).

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

INS_HNTC2_MODE: Harmonic Notch Filter dynamic frequency tracking mode

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. Dynamic harmonics 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 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.

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.

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.

SERIAL4_BAUD: Serial 4 Baud Rate

The baud rate used for Serial4. Most stm32-based boards can support rates of up to 1500. If you setup a rate you cannot support and then can't connect to your board you should load a firmware from a different vehicle type. That will reset all your parameters to defaults.

Note: This parameter is for advanced users

This sets a timeout for serial pass-through in seconds. When the pass-through is enabled by setting the SERIAL_PASS1 and SERIAL_PASS2 parameters then it remains in effect until no data comes from the first port for SERIAL_PASSTIMO seconds. This allows the port to revent to its normal usage (such as MAVLink connection to a GCS) when it is no longer needed. A value of 0 means no timeout.

To be useful the ground station must support TERRAIN_REQUEST messages and have access to a terrain database, such as the SRTM database.

TERRAIN_SPACING: Terrain grid spacing

Note: This parameter is for advanced users

Distance between terrain grid points in meters. This controls the horizontal resolution of the terrain data that is stored on te SD card and requested from the ground station. If your GCS is using the ArduPilot SRTM database like Mission Planner or MAVProxy, then a resolution of 100 meters is appropriate. Grid spacings lower than 100 meters waste SD card space if the GCS cannot provide that resolution. The grid spacing also controls how much data is kept in memory during flight. A larger grid spacing will allow for a larger amount of data in memory. A grid spacing of 100 meters results in the vehicle keeping 12 grid squares in memory with each grid square having a size of 2.7 kilometers by 3.2 kilometers. Any additional grid squares are stored on the SD once they are fetched from the GCS and will be loaded as needed.

TERRAIN_OFS_MAX: Terrain reference offset maximum

Note: This parameter is for advanced users

The maximum adjustment of terrain altitude based on the assumption that the vehicle is on the ground when it is armed. When the vehicle is armed the location of the vehicle is recorded, and when terrain data is available for that location a height adjustment for terrain data is calculated that aligns the terrain height at that location with the altitude recorded at arming. This height adjustment is applied to all terrain data. This parameter clamps the amount of adjustment. A value of zero disables the use of terrain height adjustment.
