QZSS

The Quasi-Zenith Satellite System (QZSS) is a Japanese satellite navigation system designed to improve positioning accuracy in urban and mountainous areas where GPS signals may be weak or blocked. QZSS consists of several satellites that orbit the Earth and transmit signals to receivers on the ground. It enhances GPS by providing additional signals and improving timing, which is particularly beneficial in densely populated regions. The system supports various applications, including autonomous vehicles, disaster management, and agriculture, offering users precise location information and enhancing overall navigation capabilities.
