PROBLEM TO BE SOLVED: To provide an autonomous travel system in which a mobile station acquires position information using positioning correction information based on positioning performed at a base station, and a constitution for communication is simplified to be easily used by users.SOLUTION: An autonomous travel system allows a tractor 1 to autonomously travel along a route predesignated by a communication terminal. The tractor 1 includes a control unit 4 that allows the tractor 1 to autonomously travel, a positioning information acquisition unit 52 that acquires positioning information on the basis of radio waves received from respective satellites 105, 105 and a first near field communication unit 51 that communicates with a wireless communication terminal 46. The wireless communication terminal 46 includes a route production unit that produces the route, acquires positioning correction information from a broadcast server 85, and transmits the positioning correction information to the first near field communication unit 51.SELECTED DRAWING: Figure 3COPYRIGHT: (C)2019,JPO&INPIT【課題】基準局での測位に基づく測位補正情報を用いて移動局で位置情報を取得する自律走行システムにおいて、通信のための構成を簡素化し、ユーザにとって利用し易いものにする。【解決手段】自律走行システムは、通信端末によって予め設定された経路に沿ってトラクタ1を自律走行させる。トラクタ1は、当該トラクタ1を自律走行させる制御部4と、衛星105,105,・・・から受信した電波に基づいて測位情報を取得する測位情報取得部52と、無線通信端末46と通信を行う第1近距離無線通信部51と、を備える。無線通信端末46は、前記経路を生成する経路生成部と、配信サーバ85から測位補正情報を取得して、当該測位補正情報を第1近距離無線通信部51に送信する。【選択図】図3
