SUMMARY

This discussion focuses on calculating the Right Ascension of Ascending Node (RAAN) and the argument of perigee for a satellite using given orbital parameters. The user has provided values such as period, inclination, apogee, perigee, semi-major axis, and eccentricity. To determine RAAN, one must measure the angle from the First Point of Aries to the ascending node in an eastward direction. For the argument of perigee, the angle is measured from the ascending node to the perigee.

PREREQUISITES
  • Understanding of orbital mechanics
  • Familiarity with satellite orbital parameters
  • Knowledge of RAAN and argument of perigee definitions
  • Ability to interpret angles in celestial navigation
NEXT STEPS
  • Study the calculation methods for RAAN using orbital elements
  • Research the significance of the First Point of Aries in celestial mechanics
  • Learn about the implications of eccentricity on satellite orbits
  • Explore tools for simulating satellite orbits and calculating orbital parameters
USEFUL FOR

Aerospace engineers, satellite operators, and students of orbital mechanics seeking to understand satellite positioning and trajectory calculations.

I have some values and by using them I need to find the RAAN and argument of perigee of a satellite. I have the period, inclination, apogee and perigee (as values not vectors), found semi-major axis and the eccentricity, but facing difficulty on how to proceed on calculating RAAN and the argument of perigee!
any help will be greatly appreciated

For the RAAN, you'll need to take the reference direction into account (First Point of Aries), and measure the angle from that to the ascending node in an eastward direction.

For the argument of perigee, measure the angle from the ascending node to the perigee.
