Abstract: In CTCS-3 and ETCS-2, on-board equipment determines the train position and running direction based on the last relevant balise group, and reports the train position to Radio Block Center (RBC). RBC sends train control information such as movement authority to the train according to the train position, so as to jointly ensure the safe and efficient operation of the high-speed trains. This paper introduces the basic concept, basic principle and method of calculating train position and direction based on the last relevant balise group, expounds the basic concepts of location and direction in the on-board equipment location report, analyzes the state transition relation of train position and direction in different scenarios, and analyzes and introduces the general calculation method of train position and direction.

Key words: Chinese Train Control System (CTCS), European Train Control System (ETCS), on-board equipment, last relevant balise group, train position, train direction
