A Beidou PPP-RTK train full-scene positioning method, comprising the following steps: when the train is in an open or semi-sheltered scene, a train positioning terminal combines Beidou PPP-RTK with initialized INS to position the train and obtain train position information; when the train enters a full-sheltered scene, the train positioning terminal receives a UWB base station signal, then constrains the height of the train in advance, and then establishes a height-constrained UWB model, and then obtains the position information of the train through the height-constrained UWB model and the initialized INS; when the train leaves the full-sheltered scene, the train positioning terminal receives PPP-RTK correction information and a UWB base station signal, establishes a height-constrained PPP-RTK model, obtains the positioning result of the PPP-RTK, and thus obtains the position information of the train. The train positioning accuracy is high in a complex scene.
