Control Segment

The control segment is responsible for constantly monitoring satellite health,
signal integrity, and orbital configuration from the ground. The control segment
includes the following sections:
• Master control station
•

Monitor stations

• Ground antennas
Monitor Stations
At least six unmanned monitor stations are located around the world. Each
station constantly monitors and receives information from the GPS satellites
and then sends the orbital and clock information to the master control station
(MCS).

Master Control Station (MCS)

The MCS) is located near Colorado Springs in Colorado. The MCS constantly
receives GPS satellite orbital and clock information from the monitor stations.
The controllers in the MCS make precise corrections to the data as necessary,
and send the information (known as ephemeris data) to the GPS satellites using
the ground antennas.
