Perturbation effects on sun-synchronous orbit

WebThe geosynchronous synthetic aperture radar (GEO SAR) is susceptible to orbit perturbations, leading to orbit drifts and variations. The influences behave very differently from those in low Earth orbit (LEO) SAR. In this paper, the impacts of perturbations on GEO SAR orbital elements are modelled based on the perturbed dynamic equations, and then, … WebUnderstanding planetary perturbations is easier when you imagine them in the correct frame. Imagine a frame centered on the real planet. One axis points away from the sun, the other is perpendicular to the first, in the "leading" direction of motion. Distances are measured in km or in AU.
