Spirent Communications’ Positioning Technology Division, Paignton, UK, has announced that the Japanese Aerospace Exploration Agency (JAXA) has selected Spirent’s GSS8000 Multi-GNSS Constellation Simulator to support further development of the Quazi-Zenith Satellite System (QZSS) program.
Responsible for the development of the initial QZSS user equipment, JAXA is using the GSS8000 to verify QZSS receiver performance.

Responsible for the development of the initial QZSS user equipment, JAXA is using the GSS8000 to verify QZSS receiver performance.
The highly elliptical orbits of QZSS allow satellites to dwell at high elevations, transmitting a variety of signals to coverage in urban canyons and providing additional overhead ranging sources in Japan. Consequently, JAXA needed to design receivers that supported multiple satellite technologies, including capabilities test GPS at L1, L2 and L5 signals as well as QZSS signals at the same frequencies.
The Spirent simulator includes a wide range of software modeling capability to enable the receivers to be tested under extreme and error conditions as well as in normal performance test cases.
