Position estimating device, position estimating system, and position estimating method

A position estimating method comprising:

• obtaining a plurality of position data of a transmitter, the plurality of position data being output from respective positioning devices;
• calculating a density of the plurality of position data based on the plurality of position data output from the respective positioning devices obtained by the obtaining, the density of the plurality of position data being a value indicating how close positions indicated by the plurality of position data are;
• and
• estimating a position of the transmitter based on the plurality of position data output from the respective positioning devices and the density calculated by the calculating.
