JAXA Chooses Spirent’s GSS8000 to benchmark their QZSS receiver performance

In a recent post I explained the concept behind QZSS (What is QZSS) – Since the publication of that post and to further help in the development of the Quazi-Zenith Satellite System (QZSS) programme, the Japanese Aerospace Exploration Agency (JAXA) has selected Spirent’s GSS8000 Multi-GNSS Constellation Simulator to verify QZSS receivers. The highly elliptical orbits of QZSS allow satellites to dwell at high elevations, improving coverage in urban canyons and providing additional overhead ranging sources in Japan. JAXA needed to design receivers that supported multiple satellite technologies. After several discussions with Spirent we provided JAXA with a solution that not only included testing capabilities for GPS at L1, L2 and L5 signals but also tested performance of QZSS signals at the same frequencies.

If you are working on QZSS and would like more information on Spirent’s QZSS test solution contact us.
