Movement amount estimation device, movement amount estimation method, and computer readable non-transitory storage medium storing movement amount estimation program

By a movement amount estimation device, a movement amount estimation method, or a computer-readable non-transitory storage medium storing a movement amount estimation program, a degree of a priority of a combination of each of past satellite data acquired by a receiver at a plurality of past points and current satellite data acquired at a current point, for using the priority for estimating a movement amount is determined, and a relative movement amount from at least one of the plurality of past points to the current point is calculated.
