Abstract: A first positioning processing unit executes independent positioning for calculating the position of a work vehicle on the basis of a satellite signal received from a satellite. A transmission processing unit transmits point positioning information to a base station server that selects one base station. An acquisition processing unit acquires correction information associated with the one base station from the base station server. A second positioning processing unit executes RTK positioning for calculating the current position of the work vehicle on the basis of the correction information. When the RTK positioning for the work vehicle based on first correction information associated with a first base station becomes possible, the transmission processing unit transmits, to the base station server, the point positioning information immediately before the RTK positioning becomes possible.

Abstract: The display system for remote control of a working machine includes a plurality of camera units and an image processing device, both provided on or in a working machine, and a display device and a remote control device, both provided in the remote control side. The display device detects movement of the head of an operator and transmits the detected movement of the head of the operator to the remote control device. The remote control device transmits, to the image processing device over wireless communications, the movement of the head of the operator transmitted from the display device. The image processing device adjusts, for transmission to the display device, parts of left-eye and right-eye panoramic images according to the movement of the head of the operator transmitted from the remote control device.
