RAAN influences which aspects of a satellite's orbit?

• A. The altitude and speed of the satellite
• B. The orientation of the orbital plane and the ground track behavior
• C. The satellite's mass and drag coefficient
• D. The communication frequency with ground stations

Answer: (B)

The main idea is that RAAN tells you where the orbital plane is pointed in space. It’s the angle from a fixed celestial reference direction to the point where the orbit crosses the equator heading northward (the ascending node). That orientation of the plane sets how the orbit intersects Earth’s surface, so as the planet spins beneath, the satellite traces different ground tracks. In other words, RAAN changes where the orbit passes over different longitudes and how the ground track appears, without changing how high the satellite is or how fast it moves. It also doesn’t relate to the satellite’s mass, drag, or the communication frequency you use.
