Strange "blips" when using FOB

[mspusch]

another option is obviously that there is something wrong with your FOB.
do you get those jumps when you look at just the FOB data?
did you try contacting Ascension about it? Maybe they have seen this problem before.

we have not seen this exact problem before, just in general have seen the FOB be jittery when the sensors are more than 2-3 feet away from the receiver. jitter increases with distance.

as for a fix/workaround, you could intercept the FOB data in Vizard and write an algorithm that ignores sudden large changes by just interpolating and predicting the 'assumed' data for those intervals.
it looks like your 'jumps' are very short, so you would only have to interpolate for a few frames, as after that the data is good again.
there is a good chance that such a workaround will fix your problems well enough so that you can do your experiments without problems.
