Deep Space Station 14, a 70-meter radio telescope at the DSN's Goldstone Deep Space Communication Complex

Additional status information is displayed in the ground data system. This ground data system consists of the Deep Space Network, the Ground Communications Facility -- which sends data between JPL and the Deep Space Network sites worldwide -- and the computer systems located at JPL. Once the spacecraft's telemetry is received and sorted through the ground data system, selected measurements from it are displayed on a workstation so mission control can verify that the spacecraft is healthy and has received its latest set of commands.

Telemetry is the type of data that carries the status of voltages, pressures and temperatures within the spacecraft's subsystems. Telemetry also carries the bulk of the scientific measurements, such as images and spectra produced by the spacecraft's instruments.
