Hi,

As I am testing out the Sentinel outdoors, I came across an issue where the Sentinel rejected Position mode. I have calibrated all the sensors multiple times and made sure it has GPS lock (~20 satellites with HDOP < 1). The only way I mitigated this issue was by enabling the qvio server. In my understanding, you do not need to run the qvio server to enable Position mode outside. Any suggestions/advice to fix this issue?

FYI Sentinel has not been flown indoors yet.

Thanks!

Hi @rohitpillai ,

Sorry you're having an issue.

Did you happen to update the parameters for outdoor mode? You can try these: https://gitlab.com/voxl-public/flight-core-px4/px4-parameters/-/blob/master/helpers/v1.12/ekf2_outdoor_gps_mag.params

The aid mask parameter is mainly responsible for changing position modes to use vision versus gps. 

We might have a gap in our docs to make this more clear if it wasn't ther. 

You're right you don't need vision for outdoor flight mode.

Thanks,
Rich

Yep uploading this param file worked!

Thanks!
