Abstract

See full text

A controller provided to a work machine stores a plurality of mask ranges which are used to select positioning satellites to be used by a receiver to compute a position of an antenna and are set with reference to an antenna on the basis of the postures of a work device and an swing structure. The controller computes each of a plurality of positioning precisions on the basis of satellite related data on the positioning satellites each of which is selected through use of each of the plurality of mask ranges and satellite related data on the positioning satellites which are selected through use of none of the plurality of mask ranges. The receiver computes the position of the antenna on the basis of satellite signals of the positioning satellites selected in a case of having the highest positioning precision out of the plurality of computed positioning precisions.
