Which system allows users to determine their exact position on or above the Earth?

• A. Geographic Information System (GIS)
• B. Global Positioning System (GPS)
• C. Remote Sensing System (RSS)
• D. Mapping and Analysis System (MAS)

Answer: (B)

The Global Positioning System (GPS) is designed specifically to determine precise locations on or above the Earth's surface. It achieves this through a network of satellites that transmit signals to GPS receivers, which then use these signals to triangulate their exact position based on the time it takes for the signals to travel. In contrast, while a Geographic Information System (GIS) is valuable for analyzing and managing spatial data, it does not directly provide real-time positional data like GPS. Remote Sensing Systems (RSS) involve acquiring data about the Earth's surface via satellite or aerial sensors, primarily for analysis rather than real-time positioning. Similarly, Mapping and Analysis Systems (MAS) focus on creating and analyzing maps but do not inherently include the capability to pinpoint a location in real time like GPS. Thus, GPS is uniquely suited for the task of determining exact positions, making it the correct choice.
