PROBLEM TO BE SOLVED: To provide an acceleration measuring device capable of determining the acceleration of a reception point by utilizing a concept of indefiniteness based on a newly defined indefinite value even when using data with a limitation on a range by limitation on the data size. SOLUTION: An acceleration calculation part 3 calculates an acceleration component of a carrier phase based on data for positioning including data of the carrier phase. Subsequently, the acceleration calculation part 3 calculates an indefinite value of the acceleration component of the carrier phase according to the data size or time interval of the data of the carrier phase. Then, the acceleration calculation part 3 calculates an acceleration component of the carrier phase whose indefiniteness is resolved by adding the indefinite value to the acceleration component of the carrier phase, and calculates the acceleration of the reception point based on the calculated acceleration component and direction cosine.
