Abstract
A relative position calculating system for work machines includes a first dump truck (101) which receives a navigation signal from at least one of a plurality of satellites (120), a second dump truck (111) which receives a navigation signal from at least one of the plurality of satellites (120), and a relative position calculating apparatus (102) which calculates a relative position between the first dump truck (101) and the second dump truck (111) based on the navigation signals which the first dump truck (101) and the second dump truck (111) receive, respectively, from a common satellite of the plurality of satellites (121). Thus, an influence of a positioning error due to a satellite positioning system is reduced, and accuracy of a calculation for the relative position between the two dump trucks (101, 111) can be enhanced.
