PROBLEM TO BE SOLVED: To enable positioning by using a satellite positioning system as inexpensive as possible when carrying out an accompanying work between a first work vehicle and a second work vehicle.SOLUTION: An accompanying work system is provided in which a first satellite positioning system is mounted at one of a first work vehicle and a second work vehicle, and a second satellite positioning system inferior in accuracy in comparison with the first satellite positioning system is mounted in a remote controller that is brought into the other work vehicle. Current positions of the first work vehicle and the second work vehicle are measured by use of the first satellite positioning system and the second satellite positioning system so that positions of the first work vehicle and the second work vehicle are shown in a display unit of the remote controller.SELECTED DRAWING: Figure 1COPYRIGHT: (C)2016,JPO&INPIT【課題】第一作業車両と第二作業車両とにより併走作業を行うときに、できるだけ安価な衛星測位システムを利用して測位し作業できるようにする。【解決手段】第一作業車両と第二作業車両の一方の作業車両に第一衛星測位システムを搭載し、他方の作業車両に持ち込む遠隔操作装置には前記第一衛星測位システムよりも精度の低い第二衛星測位システムを搭載し、第一衛星測位システムと第二衛星測位システムにより、第一作業車両と第二作業車両の現在位置を測位して、第一作業車両と第二作業車両の位置を遠隔操作装置の表示装置に表示する。【選択図】図１
