The data is broadcast via the QZSS to high-precision positioning receivers installed in automobiles that can detect locations with centimeter-level accuracy.
Multi-GNSS: GPS, GLONASS, Galileo, and QZSS testing
As a true five-constellation technology using GPS, GLONASS, BeiDou, QZSS and now Galileo observations, Trimble VRS Now delivers even better real-time positioning performance for customers using Trimble networks throughout much of Europe.
The Spirent GSS8000, which is already widely used to test GPS, GLONASS, Galileo, SBAS and QZSS technology, enables easy set-up and control of simulated Compass constellations.
As a true five-constellation technology that uses GPS, GLONASS, BeiDou, QZSS and now Galileo satellites, Trimble RTX delivers improved real-time positioning performance to its users worldwide.
Users can now benefit from record and playback of two channels of serial digital data alongside the digitized GPS L1, GLONASS L1 and even QZSS signals.
The QZSS will be formed from a constellation of Japan's positioning satellites, developed by Mitsubishi Electric, which will be in geosynchronous orbit with an inclination of 45 degrees in order to pass near their zenith over Japan and also pass above the Asia-Oceania region, thus providing seamless service regardless of geography.
Spirent was the first to bring QZSS simulation to market on its GSS8000 platform in 2009.
Japanese Aerospace Exploration Agency (JAXA) Uses Spirent Solution to Benchmark QZSS Receiver Performance
GNSS chip supports GPS, GLONASS, QZSS and SBAS and delivers exceptional sensitivity and acquisition times.
Only simulators can fully test partially deployed GNSS constellations such as Galileo and QZSS, and future signals such as L5 and L2C on GPS.
Classified testing for GPS is available to authorized users, and the GSS8000 architecture is designed to support future upgrades for Compass, QZSS and GLONASS L3 signals.
