Modern experiments in High Energy Physics are tend to increase the amount of data to be processed, thus, the speed of the algorithms become crucial. However, the efficiency and precision of the applied procedures can not be compromised. Therefore, the Kalman filter method is usually used as the core for the reconstruction of collision, as it satisfies all the requirements.
Current implementations of the Kalman filter method to the reconstruction of charged particle trajectories are based on the assumption of the 2D measurements with the third coordinate fixed. Such an approach leads to the strong dependency of the fitting procedure on the geometry of the experiment.
In the current work the 3D Kalman filter based track fit is developed, which operates with 3D measurements of 3 independent coordinates. The algorithm shows correct results with pulls of unity width and flat distribution of the prob-function.
