Title: Harumasa Hojo: Innovator in Navigation and Positioning Systems

Introduction

Harumasa Hojo, a distinguished inventor located in Tokyo, Japan, is known for his significant contributions to the fields of navigation and positioning technology. With two patents to his name, Hojo has made advancements that enhance the accuracy and functionality of measuring distances and positions.

Latest Patents

One of Hojo's latest inventions is an ultra-sensitive system for measuring distance or position. This innovative system utilizes a combination of multiple UWB (Ultra Wideband) transmitter-receiver units that periodically transmit pseudonoise (PN) codes from known positions. By synchronizing these units with a server, and utilizing an RF tag attached to a moving object, the system can accurately determine 3-dimensional position through synchronous summation and correlative calculation using reflected signals from the RF tag.

Another significant patent is for a GPS/self-contained combination type navigation system designed for vehicles. This system enhances vehicle navigation by integrating data received from more than three satellites simultaneously with self-contained navigation data. By calculating both GPS type and self-contained type velocity data, the system can determine the vehicle's current position accurately. It intelligently voids GPS velocity data if differences exceed a specified threshold, ensuring reliable navigation under varying conditions.
