OREANDA-NEWS. June 24, 2011. NEC Corporation (NEC; TSE: 6701) announced today its provision of positioning signal technologies for the first Quasi-Zenith Satellite (QZS), "MICHIBIKI," (*1) operated by the Japan Aerospace Exploration Agency (JAXA).

NEC's responsibilities include the design and development of a "high precision positioning test system" (positioning system) and a "trucking control system," which controls the satellite from the ground.

MICHIBIKI's positioning signals are provided by an NEC positioning system that JAXA adopted in December 2010 for verifying technologies. JAXA has now confirmed both the quality and reliability of L1-C/A and L2C (*2) positioning signals, which allows the alert flags (*3) for these signals to be removed, and enables MICHIBIKI compatible GPS receivers to use the satellite's signals for calculations.

Looking forward, NEC will continue leveraging the most advanced space technologies as part of advancing the operations and improving the performance of this quasi-zenith satellite and fostering the realization of an information society friendly to humans and the earth.
