Choose the source of the orbit
Use Load OEM to read a CCSDS ephemeris file, Live Stream to follow a spacecraft in real time, or My Designs to take the orbit of one of your mission designs or studies.
Read the ground track
The Ground Track shows where the spacecraft passes. The summary gives altitude, inclination, period and eclipse figures.
Check the passes
Pick the ground stations of the list, for example Kiruna, Kourou, Hartebeesthoek or Fairbanks. The Active Passes table gives each contact with its duration and maximum elevation. The Events list shows other events in the propagation.

Good to know

Under My Designs, a Concurrent Engineering Design study loads its orbit and its 3D satellite. The design flies along the orbit and plays at once. For a study with several satellites, the whole constellation is shown, with a bright dot for each satellite and the rings of its planes. Choose the satellite to follow in the list. Press Follow the satellite to move the camera with it and look at it close up, and use the size slider to make it bigger or smaller. It is drawn much larger than it is, so that it can be seen. Press Back to the Earth to see the whole orbit again.
