Module 3: Lecture 3 GPS

GPS

(Global Positioning System) a systems of satellites, ground stations, and receivers that allow one to identify their position on the surface of the Earth

accuracy vs precision

accuracy: how close experimental value is to accepted value; precision: how closely measured values agree with each other

GPA Space Segment

a constellation of Navstar satellites that orbit the Earth and transmit radio signals to receivers

GPS Control Segment

(ground stations monitoring and managing the satellites)

GPS User Segment

(GPS receivers in devices like phones and watches that receive signals to determine location)

GPS Segments 3)

space segment, control segment, user segment
