C.Israel
A.Australia
D.Japan
B.Canada
Correct Answer: Option D
Satellite navigation systems rely on measuring the distance between navigation satellites and the user's receiver.
Currently, there are four global systems:
- GPS from the USA
- GLONASS from Russia
- Galileo from the European Union
- BeiDou from China
In addition, there are two regional systems:
- NavIC from India
- QZSS from Japan
Global navigation systems serve users worldwide, while regional systems are designed for users within a specific service area.
Therefore, Japan has its own Satellite Navigation System (QZSS).
Hence option (d) is the correct answer.
