Did You use Guidance along with a DJI flight controller? Also, the precision is heavily influenced by the environment. Good lighting, rich texture and regular motion should give You reasonably...

Guidance has a poor onboard IMU. Try to connect Guidance with a DJI flight controller. A3 should also work.

The UART example should also work with ROS with little modification, although we don't recommend this approach, since the UART interface is designed for very simple MCU's.
