Abstract: This paper discusses the current positioning methods of rail transit and the advantages of satellite positioning, analyzes the needs of pre-positioning of marshalling station shunting locomotive, and studies a satellite pre-positioning algorithm suitable for marshalling station shunting locomotive automation system. The pre-positioning efficiency and accuracy of the marshalling station shunting locomotive is improved through satellite initialization positioning and positioning section verification.

Key words: satellite positioning, marshalling station, shunting locomotive
