Questions and Answers

What does the true anomaly define?

  • The orientation of the orbit within the orbital plane
  • The point where the satellite is closest to the Earth
  • The angle from the ascending node to the perigee from Earth's center
  • Where within the orbit the satellite is at a given point in time (correct)

    • What is the significance of the perigee?

  • It is where the satellite is going down (south)
  • It is the point where the satellite is farthest from Earth
  • It is the point where the satellite is closest to Earth (correct)
  • It defines the satellite's orientation within the orbital plane

    • What is the role of the ascending node in an orbit?

  • Marks where the satellite is going up (north) (correct)
  • Calculates the distance between satellite and Earth
  • Determines the argument of the perigee
  • Defines the inclination of the orbit

    • Which angle defines the tilt between the orbital plane and the equatorial plane?
