ABSTRACT:
An angular velocity calculating apparatus which is low-priced and capable of obtaining an angular velocity with high accuracy is realized. Two velocity detectors which are substantially small in offset error, noise, or the like, unlike the conventionally employed gyroscope, is disposed at portions on the moving matter or in the vicinity thereof, and the angular velocity is obtained on the basis of the velocity information obtained from these detectors. Accordingly, the angular velocity calculating apparatus and a navigation apparatus can be realized which is higher in accuracy and cheaper as compared with the conventional ones.
