Each station in the worldwide tracking network was clearly shown with a circle. Above the world map were five clocks that showed, from left to right, Greenwich Mean Time, orbit number, countdown time, elapsed time and time to retrofire. To each side of the world map display was a large trend chart that displayed telemetry data from all of the worldwide tracking stations.
