CST Level 1 Land Surveyor Certification Practice

The QZSS, or Quasi-Zenith Satellite System, is a satellite-based navigation system developed and operated by Japan. Its main purpose is to enhance GPS capabilities in Japan and the Asia-Oceania region, particularly improving satellite positioning in urban canyons and under dense foliage. The system consists of multiple satellites positioned in orbits that allow them to be visible from Japan and surrounding areas for most of the day. This makes it particularly advantageous for applications where precise positioning is critical, such as in various sectors like transportation, agriculture, and disaster management.

The other countries mentioned operate their own navigation systems but are not involved with the QZSS. The United States operates the GPS system, China has the BeiDou Navigation Satellite System, and Russia operates GLONASS. Each system serves its respective regions and applications, but the QZSS specifically is a project of Japan, reflecting the country's technological advances and strategic interests in fostering reliable navigation solutions.
