Title: Kenji Kataoka: Innovator in Satellite Positioning and Train Detection Technologies
Introduction
Kenji Kataoka is a prominent inventor based in Tokyo, Japan. He has made significant contributions to the fields of satellite positioning systems and train detection technologies. With a total of 9 patents to his name, Kataoka's work has had a substantial impact on modern technology.
Latest Patents
One of Kataoka's latest patents is a satellite positioning system receiver capable of detecting failures in the RF receiver unit, including the receiving antenna. This innovative system utilizes a test signal generator to create a first test signal, which is transmitted and received by an RF receiver unit. The system generates a second test signal and a second satellite signal, allowing for the calculation of correlation values to acquire satellites. A first failure detector unit compares the signal intensity of the second test signal with a threshold to generate a failure detection signal. Additionally, a second failure detector compares the satellites acquired to determine the existence and location of any failures.
Another notable patent is a train-position detection device. This device includes a radio-wave's angle-of-arrival calculator that determines the angle of arrival of a radio wave based on a reception signal. It also features a position acquisition unit that gathers information on the installation position of ground-based wireless communication apparatuses. The train-position calculator calculates the train's position based on its movement distance, while a correction-amount-to-train-position calculator adjusts the calculated position using the angle of arrival and installation information.
