Wind Algorithm: v2.2

[sungjun han]

I want to know about the Wind Algorithm: v2.2 for drones.
Are the algorithms or formulas used in it publicly available?
Or are they confidential?
Is there an open-source version available?

Hello,

Thank you for your interest in AirData's wind algorithm.

To provide some background, the in-flight wind information is generated by AirData using the angle and speed of the aircraft at each point of the flight. The wind speed calculations are based on a 5-second average, and AirData will provide readings every 5 seconds if enough data is available. To get wind readings every 5 seconds, there needs to be stability with the wind and drone/controls. A gap in wind readings indicates that either the wind or the drone/controls were not stable enough during that period for our algorithms to accurately provide readings.

Version 2 of our wind algorithm includes several enhancements:

• A comprehensive aerodynamic profile for each drone type
• Support for all flight modes
• Higher resolution: wind data is reported at all speeds
• Improved handling of turns and altitude changes
• Better accuracy through balancing functions to compensate for non-balanced IMUs

Note: Version 2 will not report wind during sharp maneuvers, such as steep decline or fast turns.

Regarding your question about availability — the algorithm is proprietary to AirData and is not publicly available. There is no open-source version of this algorithm.

If you have further questions, feel free to reach out to us directly at sup...@airdata.com.

Thank you for your time.

Kind regards,
Teresa
