In fig. 2 the object yelocity is represented. In the case of least sąuare method, the current yelocity (ds/dt) is calculated. Kalman filter assigns the yelocity by eąuation [lj.

It is eyident that processing of GPS measurement with condition to locate a object on the track using the least sąuare method [1] does not consider all available information about the movement (e.g. character of yelocity). The measured move-ment in terms of yelocity is not continuous. The yalues are too dispersed. Negatiye
