There is a lot of possibility to improve service quality by extending the notion of a positioning system. Basic positioning systems assign locations to measurements. Advanced systems can use time-series information for refinement including Weighted Least Squares, Recursive Least Squares, Kalman filtering, and particle filtering. The main results and algorithms get a closed explanation in this chapter.
