[The vive tracker 3.0 is based on an IMU that TDK has been discontinued- the problem of occasional drifting]

It was brought to my attention that VIVE tracker 3.0 is based on the MPU 6250 TDK, which has been discontinued. Does anybody think that using an absolute orientation high performance IMU like the Bosch BNO80x series will solve problems with occasional drifting of the vive tracker?

thank you

I will look into it. thank you for the explanation. It is appreciated.

Yes, we use 4 base stations. How do you "dial in a very precise pose in the universe"?

We are a startup company and have managed to build a VR surgical training system that tracks motion accurately and without "tremor" using tracking algorithms for the area of interest which is about 50 x 50 x 50 cm. The motion is excellent, the Vive newest trackers are attached on real surgical instruments and the user has haptic feedback from the surgical instruments along with the VR experience. These instruments go into a plastic anatomic model - human body- through holes. There is a snapping process on the software side that allow us to have a fixed point of rotation like in real endoscopic surgery. MOST OF THE TIME the system works fine. Occasionally, when for example the computer goes into sleep mode, or we restart the computer, this excellent accuracy which is within mm is lost and the tracking is off by 3 cm. This happens consistently only on side of the plastic model, let's say the right side. Our question : how can this be random? Is there a way to avoid it? We have invested 2.5 years in R&D and everything else works perfectly. Could it be related to the Accelerometer's g range (embedded into Vive) ? I would assume that for the slow movements we are doing a low g range is required? Any input will be appreciated?
