Aircraft model: DJI Mavic 3E
Controller: DJI RC Enterprise Pro
Android Studio Version: Android Studio Giraffe | 2022.3.1 Patch 4 November 16, 2023
Gradle: 7.4.2

Hello everyone,

 

I have a question regarding the control frame rate for DJI drones. Specifically, I'm interested in understanding the frequency at which the drone can receive and act on new instructions. Knowing this would help me better understand the responsiveness and precision I can expect when operating with the drone.

 

Thanks in advance for your assistance!

  Dear developers, Hello, thank you for contacting DJI Innovation. The control frequency of the drone is related to the call frequency of the SDK, which is usually around 10HZ, that is, 0.1s I hope our solution can help you, thank you for your email, wish you a happy life! Best Regards, Dji innovation SDK technical support

  Dear DJI Team,

  Thank you for your reply.

  Could you please clarify what you mean by “the call frequency of the SDK”? Does this frequency represent a hard limit imposed by the SDK or is there a way to achieve higher control frequencies?

  The 10 Hz rate you mentioned seems quite low for our use case. For example, in step-wise control scenarios, sending velocities at only 10 Hz means the drone will operate with a constant commanded velocity for 0.1 s, which significantly reduces precision in positioning.

  Based on my experience with other robotics systems, a control frequency of 50 Hz is generally optimal for achieving precise and responsive behavior. I would like to know if it’s possible to achieve a higher control frequency, such as 50 Hz, with the MSDK or if 10 Hz is a fixed limitation.

  Looking forward to your clarification.

  Dear developers, Hello, thank you for contacting DJI Innovation. Yes, this frequency has limitations and cannot be modified by oneself. It can only be around 10Hz, or it may not be precise to exactly 10Hz. I hope our solution can help you, thank you for your email, wish you a happy life!
