Who is it for?

QZSS is open to the general public, and is free for anyone to use any day, any time. 

Benefits of satellite positioning is received by most of us unknowingly, when using our smartphones. Satellite positioning can also be used to boost productivity in many industries from logistics, construction, farming, emergency response, gaming and more.


How is it used?

Positioning information on its own is incredibly versatile, but using it together with other IoT devices and other datasets, can enable even smarter decision-making. 

How will you use GNSS? Put yourself to the test by joining the next RPD Challenge to create innovative solutions to change your world.


What is EWS
(Emergency Warning Service)?

Michibiki provides Emergency Warning Service, which delivers disaster information via quasi-zenith satellites to digital signage, onboard equipment, and other various devices in the event of a natural disaster. This service is to be placed-in-service in 2025.

What is MADOCA
(Multi-GNSS Advanced Orbit and Clock Augmentation)?

Multi-GNSS Advanced Orbit and Clock Augmentation - Precise Point Positioning (MADOCA-PPP):

To provide highly precise positioning augmentation services that can be used in Asia-Oceania Region, errors caused by positioning satellites are computed using observation data from domestic and overseas GNSS monitoring station networks such as IGS and MIRAI, and obtained correction data is transmitted from QZSS as L6 signal. The service is scheduled to begin trial service on September 30, 2022, and operational service in FY2024 after QZS 5-7 will be launched.
