Objectives:

  • After completing this lesson, the student will be able to describe the use of a satellite ephemeris in predicting a satellite’s trajectory, how it drives orbital operations of a satellite, and gain knowledge on performing satellite maneuvers.

  • Describe what an ephemeris is and how an ephemeris is used onboard a satellite

  • Explain why a satellite’s ephemeris degrades over time

  • Discuss the operational importance of updating an ephemeris

  • Describe the different types of satellite maneuvers and when each is used

  • List the typical sequences for conducting a maneuver and the role/responsibility of each console position

  • Discuss the operational need for performing a collision avoidance maneuver

  • Discuss how the operational timing of a thruster firing/burn critically affects the desired outcome

  • Understand the process for building and executing a maneuver command sequence
