PROBLEM TO BE SOLVED: To provide an antenna which allows persons who are passing by the work place of a work vehicle to easily realize that the work vehicle is autonomously travelling and to recognize the contents of the work which the work vehicle is doing and the travelling state of the work vehicle.SOLUTION: An antenna unit 50 for a satellite navigation system is attached to an autonomously travelling work vehicle 1 which can autonomously travel and perform work along a set travel route using a satellite positioning system. In the antenna unit, the followings are integrally stored in a case 54: a mobile GPS antenna 34; a plurality of lamps 52, 52...arranged around the GPS antenna 34; a speaker 51; a circuit board 53; and an inertial measurement device 31.SELECTED DRAWING: Figure 3
【課題】作業場近くを通行する人等に対して、容易に自律走行中であることが認識でき、どのような作業や走行状態であるかを認識できるアンテナを提供しようとする。【解決手段】衛星測位システムを利用して、設定した走行経路に沿って自動的に走行及び作業を可能とする自律走行作業車両1に取り付ける衛星航法システム用アンテナユニット50であって、移動用GPSアンテナ34と、該GPSアンテナ34の周囲に配置する複数のランプ52・52・・・と、スピーカ51と、回路基板53と、慣性計測装置31とを、一体的に一つの筐体54内に収納した。【選択図】図3
