AttitudeEstimatorQ

Source: modules/attitude_estimator_q

描述

Attitude and position estimator using an Extended Kalman Filter. It is used for Multirotors and Fixed-Wing.

用法

AttitudeEstimatorQ <command> [arguments...]
 Commands:
   start

   stop

   status        print status info

wind_estimator

Source: modules/airspeed_selector

描述

This module provides a single airspeed_validated topic, containing indicated (IAS), calibrated (CAS), true airspeed (TAS) and the information if the estimation currently is invalid and if based sensor readings or on groundspeed minus windspeed. Supporting the input of multiple "raw" airspeed inputs, this module automatically switches to a valid sensor in case of failure detection. For failure detection as well as for the estimation of a scale factor from IAS to CAS, it runs several wind estimators and also publishes those.

用法

airspeed_estimator <command> [arguments...]
 Commands:
   start

   stop

   status        print status info

ekf2

Source: modules/ekf2

描述

基于扩展卡尔曼滤波器的姿态和位置估计器。 该模块同时应用于多旋翼和固定翼飞机。

The documentation can be found on the ECL/EKF Overview & Tuning page.

ekf2 can be started in replay mode (-r): in this mode, it does not access the system time, but only uses the timestamps from the sensor topics.

用法

ekf2 <command> [arguments...]
 Commands:
   start
     [-r]        Enable replay mode

   stop

   status        print status info
     [-v]        verbose (print all states and full covariance matrix)

   select_instance Request switch to new estimator instance
     <instance>  Specify desired estimator instance

local_position_estimator

Source: modules/local_position_estimator

描述

基于扩展卡尔曼滤波器的姿态和位置估计器。

用法

local_position_estimator <command> [arguments...]
 Commands:
   start

   stop

   status        print status info

Source: modules/mc_hover_thrust_estimator

描述

用法

mc_hover_thrust_estimator <command> [arguments...]
 Commands:
