Lab Objectives

The objective of this lab understand why drone calibration is important and how to calibrate a drone before using it.

Frame Type Configuration in Mission Planner

Refer to Frame Type Configuration for more details.

Accelerometer Calibration in Mission Planner

It is necessary to calibrate the accelerometer before the use of the drone, otherwise it will not navigate properly. Refer to Accelerometer Calibration for more details.

Accelerometer Calibration in Mission Planner

It is necessary to calibrate the compass before the use of the drone, otherwise it will not navigate properly. First, make sure that your accelerometer is already calibrated before calibrating the compass. Refer to Accelerometer Calibration for more details.

Radio Control Calibration in Mission Planner

RC transmitters are used to control vehicle movement and orientation. Copter and Plane minimally control throttle, pitch, roll and yaw, while on Rover we just control throttle and roll. Each of these control signals are mapped to transmitter stick/switch(s) and in turn to autopilot channels from the connected receiver. Calibrating each of the transmitter controls/channels is a straightforward process - simply move each of the enabled sticks/switches through their full range and record the maximum and minimum positions.

Refer to Radio Control Calibration Tutorial for more details.

Electronic Speed Controller (ESC) Calibration

Electronic speed controllers are responsible for spinning the motors at the speed requested by the autopilot. Most ESCs need to be calibrated so that they know the minimum and maximum pwm values that the flight controller will send. This page provides instructions for calibrating ESCs. Refer to ESC Calibration Tutorial for more details.


RC Transmitter Flight Mode Configuration

Refer to RC Transmitter Flight Mode Configuration for more details.


Battery Parameters Calibration


These are the parameters I used for Navio2 battery configuration

You need to just to click on Pixhawk for auto configuration of the battery as explained in Navio2 doc above using either of next ground stations
