Document Type and Number:
Japanese Patent JP6417749
Kind Code:
B2
Abstract:
The present invention provides a new art for grasping a moving direction of an underwater vehicle. In order to grasp the moving direction of the underwater vehicle, a measurement apparatus 2000 is installed in an underwater vehicle 4000. An electromagnetic wave receiving unit 2020 receives an electromagnetic wave signal, which a signal outputting apparatus 3000 outputs with a first frequency, in the water. A sound receiving unit 2040 receives a sound signal, which the signal outputting apparatus 3000 outputs with a second frequency, in the water. A frequency calculating unit 2050 calculates a frequency of the electromagnetic wave signal which the electromagnetic wave receiving unit 2020 receives, and a frequency of the sound signal which the sound receiving unit 2040 receives.
