What GNSS applications are included?

The correct choice encompasses the broad range of applications for Global Navigation Satellite System (GNSS) technology, which has become integral in various fields. GNSS applications span multiple domains, including but not limited to:

• Surveying and navigation: GNSS plays a pivotal role in precise surveying tasks, allowing geodetic engineers to determine accurate positions in real-time. Navigation systems rely on GNSS for providing location tracking and route guidance, which is fundamental for transportation and logistics.

• Mapping and vehicle tracking: GNSS enables the creation of detailed maps by providing precise geolocation data, making it essential for geographic information systems (GIS). Vehicle tracking leverages GNSS technology to monitor the real-time location of vehicles, enhancing fleet management, logistics, and even personal navigation.

• The mention of "only surveying" in one of the options shows a limited understanding of GNSS applications, as it suggests that the scope of GNSS is confined to just one area, which is misleading given the versatility and importance of GNSS in multiple fields.

By recognizing that GNSS serves a diverse range of functions across various applications, the choice that includes "all of the above" accurately represents the comprehensive utility of this technology. Thus, the correct answer reflects the significant and varied
