Abstract: There is provided a positioning system for a work machine using RTK positioning that uses a satellite positioning system, the positioning system including: a sensor controller that is a calculation unit that calculates a position of an antenna, of the satellite positioning system, disposed in the work machine based on a position of working equipment, of the work machine, aligned with a known reference point PR positioned at a work site; and a monitor controller that is an initialization control unit that outputs a control command that causes a receiver, of the satellite positioning system, that performs positioning calculation by the RTK positioning to execute initialization processing of the positioning calculation in which an integer value bias of each satellite and the position of the antenna of the satellite positioning system are unknown, by using the calculated position of the antenna of the satellite positioning system.

Abstract: A construction machine control system controls a construction machine including a traveling device, a work machine having a working tool, and a swing structure to which the work machine is attached and which is attached to the traveling device to swing with respect to the traveling device. The construction machine control system includes a position detection device that detects a first position which is a position of a partial portion of the construction machine and outputs the first position as first position information; a state detection device that detects and outputs operation information indicating an operation of the construction machine; and a processing device that calculates a second position corresponding to the position of the partial portion using the first position information and the operation information and calculates a position of at least a partial portion of the work machine using second position information.
