The positions are recorded as transformation matrix which defines the model-view transformation from the plane to the camera. The transformation matrix contains translation and rotation information. The 3x4 matrix is serialized in a row-major format: T11 T12 T13 T14 T21 T22 T23 T24 T31 T32 T33 T34
The timestamp is the milliseconds since epoch (01.01.1970) and serves as a relative measure.
