Dr. Rui Hirokawa is Deputy General Manager, Space Systems Department, at Kamakura Works, Mitsubishi Electric Corporation. A fixture in today’s GNSS community, he manages several QZSS-related projects, including the centimeter-level augmentation service (CLAS), and has recently been deeply involved in the international standardization of high-accuracy GNSS. Rui Hirokawa grew up in the Tokyo suburb of Nerima, near the city’s idyllic Syakujii Park. “From my home, it took about 20 minutes, on foot and by train, to get to the center of Tokyo,” Rui said. “I remember walking a great deal as a child, with my parents and my brother, going to the park, and always finding lots of interesting things to do.”
