PROBLEM TO BE SOLVED: To provide a position estimating system estimating a symbolistic position of sensor nodes without the use of radio field intensity. SOLUTION: The position estimating system is equipped with a plurality of sensor nodes arranged arbitrarily, a track record DB, and a computing device. A plurality of sensor nodes include the key sensor nodes with symbolistic positional information and the other sensor nodes without symbolistic positional information. In the track record DB, a first alignment sensor specific information is registered for specifying the sensor nodes in the order corresponding to sense people is stored. The computing device generated groups including sensor specific information of the key sensor nodes and sensor specific information of the other sensor nodes from a plurality of sensor nodes. based on the first alignment.
