A(n) ____ is a system in which radio signals from satellites are transmitted to receivers on the ground allowing specific positions on earth to be calculated and placed on a coordinate system that can be global, regional, or local.
A) global positioning system (GPS)
B) trilateral constellation
C) electronic distance measurement (EDM)
D) geographic information system (GIS)

Question

Quizplus · Accepted Answer

The description given in the question is that of a global positioning system (GPS), which is a network of satellites that transmit radio signals to GPS receivers on the ground, allowing for accurate positioning on earth. Therefore, the best choice is A. Trilateral constellation is not a commonly used term and does not fit the description given. Electronic distance measurement (EDM) is a different technology used to measure distances between two points with high accuracy but does not involve satellite signals. Geographic information system (GIS) is a different technology used to analyze, manage, and visualize geographic data.
