Abstract
A track estimation device includes: a reliability determination unit configured to determine the reliability of satellite positioning information; an update timing determination unit configured to determine the timing of updating a parameter to estimate track of cycling based on the reliability of satellite positioning information; and an update unit configured to update the parameter based on a result of the timing determination. When the reliability determination unit determines that reliability of the satellite positioning information is low, the track estimation unit estimates the track based on the parameter by autonomous navigation.
