●What is QZSS？
Quasi-Zenith Satellite System (QZSS) is a Japanese satellite positioning system composed mainly of satellites in quasi-zenith orbits (QZO).
Satellite positioning systems use satellite signals to calculate position information. One famous example is the American Global Positioning System (GPS) and the QZSS is sometimes called the Japanese GPS.

Ratings and reviews

Great for viewing current GNSS satellites, and the AR mode is really handy for getting a sense of where satellites, however the UI is a bit dated and I would like to see a way to adjust the AR field of view so it matches the camera (you have to tilt the phone so satellites are centered to get an idea of where they truly are)

Not a bad app for gnss planning. Would be great to be able to select the Beidou B1 and B2 only though. Also a bar graph for HDOP and VDOP

Db error it says in the first launch. Doesn't work on Android 9
