CST Level 1 Land Surveyor Certification Practice

Which method utilizes satellite technology for surveying?

1. Trilateration

2. GPS

3. Differential Leveling

4. Triangulation

The correct answer is: GPS

The method that utilizes satellite technology for surveying is GPS, which stands for Global Positioning System. GPS is a satellite-based navigation system that allows surveyors to determine precise locations on the earth's surface. It achieves this by receiving signals from a network of satellites that orbit the Earth, enabling surveyors to calculate distances to these satellites and accurately pinpoint their position. GPS technology is particularly valued for its ability to provide real-time location information across large areas, significantly enhancing the efficiency and accuracy of land surveys. It transcends line-of-sight limitations and can operate in various environmental conditions, making it a preferred choice in modern surveying practices. In contrast, trilateration relies on measuring distances from known points rather than satellite signals; differential leveling focuses on establishing vertical differences in elevation using leveling instruments; and triangulation utilizes angular measurements between known points without the assistance of satellites. These methods have their unique applications but do not intrinsically leverage satellite technology like GPS does.
