摘要： Positioning in a more preferred aspect is ensured even under a situation where it is difficult to maintain a state where a wireless signal from a satellite is regularly receivable. An information processing device according to the present invention includes a first obtainer configured to obtain first information relating to an absolute position and posture in a real space of a predetermined housing, a second obtainer configured to sequentially obtain second information corresponding to a change in relative position of the housing in chronological order, and an estimator configured to estimate an absolute position in the real space of the housing at a time point at which the change in relative position of the housing indicated by the second information has been detected with the absolute position and posture of the housing corresponding to the first information as a reference.
