QZSS (Japan)

The Quasi-Zenith Satellite System (QZSS) is a satellite system developed by Japan to enhance navigation and positioning services, especially in urban areas where signals from traditional GPS satellites may be weak or obstructed. It works by providing additional satellites that are closer to the Earth and positioned to offer better coverage, particularly in cities with tall buildings. QZSS complements existing Global Navigation Satellite Systems (GNSS) like GPS, improving accuracy and reliability for various applications, including transportation, disaster response, and personal navigation devices. It plays a crucial role in ensuring precise location information across Japan and neighboring regions.
