11 Overview of QZSS (1) QZSS is a satellite positioning system operated by Japanese government as complementary and augmentation satellites of GPS. Four satellites of the first constellation has already been launched, and now the final confirmation for official service is ongoing under the starting program administrated by Cabinet Office. Functional Capability Source: GPS Complementary GNSS Augmentation Messaging Service Copyright 2018 Global Positioning Augmentation Service Corporation All Rights Reserved 10
12 Overview of QZSS (2) Visibility / Availability Four satellites constellation is consisted of three QZO (inclined geosynchronous orbit) satellites and one GEO (geostationary) satellite. Australia is located within the coverage area of QZSS service. These four satellites have started to provide experimental service of positioning technology verification. The contour shows the predicted rate of visibility for one QZO satellite over 15 degrees.
