RAAN Drift and Sun-Synchronous Precession: How Earth’s Shape Keeps Satellites in Sync with the Sun

RAAN drift caused by Earth’s J2 perturbation allows satellites to maintain sun-synchronous orbits, ensuring consistent lighting for Earth observation. This natural orbital precession eliminates the need for fuel-intensive corrections and powers global monitoring systems.
