[Movie] Why is QZSS necessary?
Introduces an overview of QZSS, GPS-related issues, and how these issues are resolved by QZSS.
[Why is QZSS necessary?]
Satellite positioning systems support navigation systems on cars, smartphones, and other devices. Satellite positioning systems calculate your distance from a satellite based on how long it takes satellite signals transmitted from GPS or other positioning satellites to arrive.

[Distance is calculated based on the time required until arrival]
According to your distance from positioning satellites, the system indicates your current position.
However, there are various issues related to the current GPS, which have limited positioning stability and accuracy. In the future it will be essential to resolve these issues to offer a wide range of services that utilize position information.
[Limited positioning stability and accuracy]
QZSS, which was developed in Japan, can resolve GPS issues of this sort.
QZS are on a figure eight-shaped orbit and are compatible with GPS, resulting in accuracy and stability that cannot be accomplished with GPS alone.
[Compatible with GPS]
[You will arrive at your destination in 30 seconds]
[Achieves accuracy and stability]
In this way the usage of services, including navigation systems on smartphones and cars, will become more stable.
[More stable positioning services]
