navigation in gps-denied enviroments

[emigomez]

Hello,

I’m developing an exploration system based on a UAV DJI with N3. The main problem is that the navigation will be indoor, and you can not make use of the GPS in any case.

Without GPS, I understand that you cannot send goto() commands directly to the OSDK-ROS as the UAV does not know where you are. Therefore I understand that you will have to use a controller that transforms the commands of goto(position_objective) to commands of attitude (roll, pitch, yaw) and acceleration of their motors (thrust), which do not require GPS.

In that case, is there a DJI controller that is implemented to use navigation without GPS? If there isn’t, could you give me some indication on what basis to do it?

Dear developer ,

Thank you for contacting DJI.

Sorry, DJI does not provide a complete solution for the indoor environment without GPS. It only provides OSDK attitude mode to control the drone. The navigation and positioning functions need to be developed by developers, If necessary, developers also need to integrate third-party sensors on the onboard computer for navigation and positioning.

Thank you for your understanding and support, hope you have a nice day.

Best Regards, DJI SDK Support Team
