Blueboat cruise speed issues

Hi all,

Wondering if anyone has had any issues with cruise speeds? I took our blueboat out for two surveys today, one in the morning where the boat was consistently going 1.5m/s and attributed it to currents, however I have taken it out just now and it was consistently going .5 (instead of 1).

It has a strong GPS connection with over 32 satellites connected. I tried restarting it, autopilot, blueOS and qGroundControl multiple times however nothing managed to fix it. Cruise speed param is set to 1m/s in blueOS and qGroundControl.

When taking over manually I can get it to go to 1m/s very easily, it does not seem like it is a physical issue with the props.

Would appreciate any insights
Cheers

Hi @Blueb -
That’s unusual - it should only go 0.5 m/s with a cruise speed of 1 m/s if the currents are strong enough that the system can’t reach that speed at full power. Do you have a .BIN autopilot log to share from that mission? I assume this was in Auto mode?

It’s worth noting that BlueOS and QGround Control are editing the same set of Autopilot Parameters…
