Usage Guide for Ardupilot
This guide mainly describes how to use SKYE2 with Ardupilot.
[!Tip] SKYE2 supports Ardupilot 4.30 and above firmware.
Flight controller parameter settings
Open Mission planner>Configuration>All parameter table; set the following parameters and save and then restart
- CAN_P1_DRIVER=1
- CAN_P2_DRIVER=1
- CAN_D1_PROTOCOL=1
- CAN_D2_PROTOCOL=1
- ARSPD_TYPE=8
- ARSPD_USE=1
- ARSPD_AUTOCAL=1
Calibrate airspeed offset
When there is no wind and the airspeed display is greater than 3m/s, please perform airspeed offset calibration before takeoff.
- Run the Mission planner software and connect the flight controller
- Make sure the pitot tube is in a windless environment
- Open Mission planner>Flight data>Action bar
- Select "Preflight Calibration" in the first check box; click the "Perform Action" button on the right
Pre-flight inspection
Before flying, please connect to the ground station to check that there is no wind and ensure that the airspeed value is within the range of 0~3m/s (if it exceeds the range, need perform airspeed offset calibration)
- Hold the pitot tube with your hand and blow air into the pitot tube. If the airspeed value changes according to the airflow speed, the inspection is complete.

Airspeed Calibration
[!NOTE] Different installation methods and airspeed sensor scale factors will be different. The airspeed indicator needs to be calibrated on the first flight.
//Enable automatic airspeed calibration - ARSPD_AUTOCAL=1
Perform calibration (choose one of the following two methods):
- Take off in QStabilize or QLoiter multi-axis mode and switch to FBWA (self-stabilizing A mode) to control the drone to fly and hover for about 5 circles. After the ground station message bar prompts that the calibration is completed, execute the landing.
- If you don’t know how to fly in FBWA mode, you can fly with the airspeed sensor enabled but without it (ARSPD_USE=1; ARSPD_TYPE=8; do not do this in an environment with high wind speed); The aircraft will fly at ground speed (relative to ground speed). After takeoff, it will circle in Loiter mode for about 5 circles. The ground station message bar will prompt that the calibration is completed before landing.
