Disclosed are an error estimation method capable of reducing a processing load, and estimating errors of indexes indicating a state of a moving object with high accuracy by using a signal from a positioning satellite. In one aspect, the error estimation method includes calculating a coordinate transformation matrix between a first coordinate system with a first sensor mounted on a moving object as a reference and a second coordinate system with the moving object as a reference, at a predetermined timing in a cycle of, converting one of an azimuth angle of the moving object based on a detection result in the first sensor and an azimuth angle of the moving object based on a detection result in the second sensor by using the coordinate transformation matrix in a case where the detection result in the second sensor receiving a signal from a positioning satellite is obtained, and estimating errors of indexes indicating a state of the moving object by using a difference between the converted azimuth angle and the other azimuth angle at the predetermined timing after a timing at which the detection result in the second sensor is obtained.
