Which segment of GPS deals with broadcasts from space?

The space segment of GPS is essential because it refers to the satellites that orbit the Earth and transmit signals to GPS receivers on the ground. The satellites in this segment are responsible for providing the precise timing and positioning information necessary for GPS functionality. They continuously broadcast the necessary data, including their location and the precise time the signals were sent, which allows GPS receivers to calculate their own position on Earth.

This role is distinct from the control segment, which involves ground stations that monitor and manage the satellites, and the user segment, which pertains to the GPS receivers used by the end-user. The signal segment is not a standard term used in GPS terminology, making it less relevant in this context. Understanding the specific functions of each segment highlights the importance of the space segment in enabling accurate and reliable navigation and positioning services.
