# 풍속 센서

고정 회선 및 VTOL 프레임의 경우 속도 센서가 *을 높게 권장합니다. 자동 조종 장치에는 실속을 감지 할 수있는 다른 수단이 없으므로이 신호는 매우 중요합니다. 고정익 비행의 경우 지상 속도가 아닌 양력을 보장하는 속도입니다.

# 하드웨어 옵션

권장 디지털 속도 센서는 다음과 같습니다.

위의 센서들은 I2C 버스/포트를 통해 연결됩니다.

Note

Additionally, the Avionics Anonymous Air Data Computer (opens new window) can be connected to the CAN bus to determine not only high-accuracy airspeed, but also true static pressure and air temperature via onboard barometer and an OAT probe.

# Enable Airspeed Sensors

Airspeed sensor drivers are not started automatically. Enable each type using its corresponding parameter:

You should also check ASPD_PRIMARY is 1 (see next section - this is the default).

# Multiple Airspeed Sensors

If you have multiple airspeed sensors then you can select which sensor is preferred as the primary source using ASPD_PRIMARY, where 1, 2 and 3 reflect the order in which the airspeed sensors were started:

  • -1: Disabled (no airspeed information used).
  • 0: Synthetic airspeed estimation (groundspeed minus windspeed)
  • 1: First airspeed sensor started (default)
  • 2: Second airspeed sensor started
  • 3: Third airspeed sensor started

The airspeed selector validates the indicated sensor first and only falls back to other sensors if the indicated sensor fails airspeed checks (ASPD_DO_CHECKS is used to configure the checks).

The selected sensor is then used to supply data to the estimator (EKF2). The EKF fuses the airspeed data if it's above EKF2_ARSP_THR and has a low innovation compared to groundspeed minus windspeed.

# Sensor-specific Configuration

Other than enabling the sensor, sensor-specific configuration is often not required. If it is needed, it should be covered in the appropriate sensor page (for example TFSLOT > Configuration).

The specific configuration for sensors that do not have a separate page is listed below:

# Calibration

Airspeed sensors should be calibrated by following the instructions: Basic Configuration > Airspeed.
