TOKYO, March 24, 2022 - Mitsubishi Electric Corporation (TOKYO: 6503) announced today that it has completed initial verification of the functions and performance of equipment aboard the QZS-1R satellite, which the company built and delivered to the Cabinet Office of Japan and is now in quasi-zenith orbit as the successor to the original Michibiki Quasi-Zenith Satellite (QZS-1).
With Quasi-Zenith Satellite System Services Inc. also having completed testing of related ground systems, the Cabinet Office will begin launching various positioning services via the QZS-1R today.
Mitsubishi Electric, in addition to supporting these services, will continue developing satellite systems that the company intends to provide for forthcoming satellites (QZS-5 to QZS-7) that will support advanced, sustainable, high-precision positioning in Japan.
