Hi , now I have this problem too. I need to do closed-loop tracking control for the ROV. But the cost of an underwater locator is too high for me. How do you solve the positioning problem through IMU? The line acceleration information I got directly from pixhaw was almost unavailable. Even when the device is standing, the acceleration information does not fluctuate around (0,0,0). “[12.9149779 7.00067566 -969.2522582]” This is a set of raw linear acceleration data taken at rest. Can you give me some advice?
Hi @southall -
Unfortunately, yo get what you pay for! Integrating IMU data to infer position is not going to be possible with the low cost motion sensors used in the Pixhawk/Navigator…
