What kind of data is position of vicon?

[philippmaa]

Hi there,
thanks for this great framework. I am new to this topic but after a while working and trying a got the tutorial running. Now I want to modify the framework to use a GPS sensor instead of vicon to meassure position. I was just wondering what kind of data for the position is given in the test file dataset.bag? is it just the difference to the last position for x,y and z in meter?
I really would appreciate your help!

Kind regards
Philipp
