Abstract
The QZSS, quasi-zenith satellite system, is a regional satellite navigation system constructed and operated by Japan. Currently, QZSS 4-satellite constellation has been operating since November 2018 and transmitting signals for several services including PNT as well as some augmentations. This paper explains the overview and future perspective of the QZSS. Over the next decade, GNSS signal authentication, QZSS-PPP service, and expansion of the service area will be accomplished with QZSS 7-satellite constellation for our safe and secure lives.
