HI,

we are using starling 2 max and are testing the vio performance.  Both vio methods performs well in handhold moving tests. We fly the drone manually in a feature-rich indoor environment. Qvio performs ok during takeoff but drifts away after some yawing motions of the drone. Open-vins drifts ~1m downwards during takeoff but maintains well after takeoff.

We need a good vio performance for indoor test, what is your recommendation? The performance is certainly affected by the imu noise, are there any setups or parameters that we can tune? 
Thanks!

I would recommend doing a barometer calibration as well via `voxl-calibrate-barometer` that tends to solve a good chunk of the altitude issues.

@Zachary-Lowell-0 Thanks! Indeed we also had the problem of height estimate unstable in px4, we will try barometer calibration.
But VIO doesnt use barometer and we still need good VIO position. Any suggestion on improving the VIO odometry output?

@Muqing-Cao 

Can you confirm your SDK version?

## Reply by Muqing Cao · 2026-01-06 00:12:25 UTC (in reply to zauberflote1)

@zauberflote1 1.5.1

@Muqing-Cao 
Please update it to the latest version, 1.6.3.

PS: 1.6.3 is still in Beta phase, but it should be released soon

@zauberflote1 thanks for your info. When will 1.6.3 be released? I see in the instruction that updating sdk will reset all config files, since we use starling 2 max, do we have to change the configs file to the startling-specific configs after update?

@Muqing-Cao 

You should be able to download it and install it, as our betas are now public.

Not necessarily, unless you changed the default values. The new SDK installation will prompt you to identify your platform.

@zauberflote1 where is beta firmware? I cant find it in the download page.

@Muqing-Cao Here is the latest beta release: https://storage.googleapis.com/platform-beta-releases/voxl2/voxl2_SDK_1.6.3-beta1.tar.gz
