Provided is a position estimation system with low power consumption. A position estimation system includes a comparison unit, a learning unit, a data acquisition unit, an inference unit, a data conversion unit, and an evaluation unit. The comparison unit has a function of calculating a first translation amount and a first rotation amount on the basis of machine learning data indicating map information. The learning unit has a function of generating a machine learning model by learning using the machine learning data, the first translation amount, and the first rotation amount. The data acquisition unit has a function of acquiring acquisition data indicating environmental information around the position estimation device. The inference unit has a function of inferring a second translation amount and a second rotation amount from the acquired data and the machine learning data using a machine learning model. The data conversion unit has a function of converting the machine learning data into evaluation data on the basis of the second translation amount and the second rotation amount. The evaluation unit has a function of evaluating the degree of coincidence between the acquired data and the evaluation data.
