I need to measure and report the current speed of the ROV.
Does anyone have any ideas how to do this?

There’s a couple ways we have measured speed of a BlueROV2:
1. Have a quadcopter follow the ROV that is just barely under the water. Get the speed reading from the UAV.
2. Use a [GPS mast](https://www.youtube.com/watch?v=cOYxxVmoFeU) that is out of the water by about 1m.
3. Use an underwater positioning system: [Water Linked UGPS](https://bluerobotics.com/product-category/sensors-sonars-cameras/underwater-gps/)
For #2 and #3, you can get speed values by selecting “Ground Speed” in the Value Widget Setup:
