MVO losing track

[Dejv311]

Hi,
I am trying to read the MVO data (odometry), but the drone keeps losing track. The values keep jumping to small (<3cm) values, which I have no idea what they represent. When the tracking works, it works great. Sometimes, after loosing track (small values for longer time) the drone spawns at entirely new location sometimes hundreds of meters away. In the picture you can see the values changing between real odometry data and the small nonsence values.

My question is:

1. Do you know what those small values represent?
2. Is there a way to achieve a reliable odometry signal?

Thank you in advance

The MVO values will do that when the MVO is unavailabe due to low light, sitting on the floor, too smooth of surface texture, etc. When they come back, they may have drifted so keep that in mind...
