Using External Systems For Position Hold

Hello from Team 76122A,
As we are preparing for Xponential, we are encountering some issues with our position hold setup. Some ideas for solving this issue would be to either use an ultrawide band transmitter on our table, or more likely an optical flow sensor added to our drone. Would this fall into the rules guidelines for the competition? If any clarification is needed, please don’t hesitate to ask.

Thank you,
Team 76122A
