Complete Parameter List

This is a complete list of the parameters which can be set (e.g. via the MAVLink protocol) to control vehicle behaviour. They are stored in persistent storage on the vehicle.

This list is automatically generated from the latest ardupilot source code, and so may contain parameters which are not yet in the stable released versions of the code.

AHRS_ Parameters

AHRS_GPS_GAIN: AHRS GPS gain

Note: This parameter is for advanced users

This controls how much to use the GPS to correct the attitude. This should never be set to zero for a plane as it would result in the plane losing control in turns. For a plane please use the default value of 1.0.

Increment

Range

AHRS_GPS_USE: AHRS use GPS for DCM navigation and position-down

Note: This parameter is for advanced users

This controls whether to use dead-reckoning or GPS based navigation. If set to 0 then the GPS won't be used for navigation, and only dead reckoning will be used. A value of zero should never be used for normal flight. Currently this affects only the DCM-based AHRS: the EKF uses GPS according to its own parameters. A value of 2 means to use GPS for height as well as position - both in DCM estimation and when determining altitude-above-home.

AHRS_WIND_MAX: Maximum wind

Note: This parameter is for advanced users

This sets the maximum allowable difference between ground speed and airspeed. A value of zero means to use the airspeed as is. This allows the plane to cope with a failing airspeed sensor by clipping it to groundspeed plus/minus this limit. See ARSPD_OPTIONS and ARSPD_WIND_MAX to disable airspeed sensors.

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.

ARSPD_WIND_GATE: Re-enable Consistency Check Gate Size

Note: This parameter is for advanced users

Number of standard deviations applied to the re-enable EKF consistency check that is used when ARSPD_OPTIONS bit position 3 is set. Larger values will make the re-enabling of the airspeed sensor faster, but increase the likelihood of re-enabling a degraded sensor. The value can be tuned by using the ARSP.TR log message by setting ARSPD_WIND_GATE to a value that is higher than the value for ARSP.TR observed with a healthy airspeed sensor. Occasional transients in ARSP.TR above the value set by ARSPD_WIND_GATE can be tolerated provided they are less than 5 seconds in duration and less than 10% duty cycle.

Note: This parameter is for advanced users

ARSPD2_TUBE_ORDR: 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.

COMPASS_EXTERNAL: Compass is attached via an external cable

Note: This parameter is for advanced users

Configure compass so it is attached externally. This is auto-detected on most boards. Set to 1 if the compass is externally connected. When externally connected the COMPASS_ORIENT option operates independently of the AHRS_ORIENTATION board orientation option. If set to 0 or 1 then auto-detection by bus connection can override the value. If set to 2 then auto-detection will be disabled.

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.

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.

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).

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.

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 t
