Japanese Aerospace Agency selects Spirent for Multi- GNSS testing

摘要

To further the development of the Quazi-Zenith Satellite System (Q2SS) program, the Japanese Aerospace Exploration Agency (JAXA) has selected Spirent Communica-tions' testing solutions to verify performance of its satellite receivers. Responsible for the development of initial QZSS receivers, JAXA is using Spirent's GSS8000 Multi-GNSS Constellation Simulator to verify QZSS re-ceiver performance. The highly elliptical orbits of QZSS al-low satellites to dwell at high elevations, im-proving coverage in urban canyons and pro-viding additional overhead ranging sources in Japan.
