GPS-Denied Indoor Flight
-
I've been having issues with flying the sentinel drone indoors with no-gps, in the following video link I fly the drone indoors and it seems to move towards the back of the drone. The flying is done in manual mode and only gave thrust commands except to avoid colliding with the walls. If there is any help that can be given for why it does this, if there is a calibration issue to a VIO issue. It also doesn't keep position in position or altitude mode. Any help or insight into the matter will be appreciated.

If by manual mode you mean literally the manual mode in PX4 then I think what you need to do is to switch to position mode (provided by qvio server is working properly) via QGC (or some other way).

@coreyazion I was able to switch to position flight mode and the drone flew better in position flight mode. In my previous testing I had issues with position flight mode with drifting but in my most recent attempt it flew much better and was relatively stable. I did experience after a short while some more drift towards the back-left of the drone however I am unsure if this is due calibration or configuration. I also experienced the same issue with PX4 Hold mode.
