Title: Innovations of Hiroyuki Toda: A Leader in GNSS Technology

Introduction

Hiroyuki Toda, based in Nishinomiya, Japan, is an accomplished inventor with a significant contribution to the field of Global Navigation Satellite Systems (GNSS). With 24 patents to his name, Toda has developed cutting-edge technologies that greatly enhance the accuracy and efficiency of movement information calculations.

Latest Patents

Among his latest innovations, Toda has patented a "Device and method for calculating movement information" that enables high-accuracy calculations without the constraints posed by the number of GNSS signals received by each of several antennas. This device comprises multiple antennas, a clock generator, several GNSS receivers, and an arithmetic logical unit. The architecture of this device allows for the sharing of a clock signal across all receivers, which significantly improves the precision in calculating movement information, including the speed of a movable body.

Another noteworthy patent is the "Positioning device, positioning system, positioning method, and positioning program," which involves high-speed determination of an integer value bias. This system utilizes carrier phase differences to compute a FLOAT solution of a specific position with respect to a secondary station, all while not relying on posture information from the primary station. The integer value bias determining section can then accurately assess the bias of the carrier phase difference based on the FLOAT solution.

Career Highlights

Hiroyuki Toda has made remarkable strides in the field while working at Furuno Electric Company Limited, where he continually pushes the boundaries of GNSS technology.
