Hello,

I am working on project to use this drone to take data, and location is critically important. I am looking for more info on this drone. Things like how accurately the drone can hold a position, how accurately it can follow a flight path, how accurately is can return to a position, (looking for specific numbers) etc.

Thanks!

Nick

For GPS flight, the m500 performance is similar to most PX4 GPS Flight. The performance is subject to standard GPS position accuracy, which is generally ~1.0 to 1.5m accurate.

For VIO flight, in a reasonably environment the typical accuracy is 1.0 to 1.5% drift over distance traveled.
