How GPS System Worksy The satellites in orbit provide the ranging signals and
data messages to the user equipment.
y The operational control segment (OCS) maintains thesatellites & tracks in space. The OCS monitors satellitehealth and signal integrity and maintains the orbitalconfiguration of the satellites. Furthermore, the OCSupdates the satellite clock corrections as well asnumerous other parameters essential to determining user
position, velocity, and time (PVT).y Lastly, the user receiver equipment performs the
navigation, timing or other related functions (e.g.surveying).
