J2Mean Object

Top  Previous  Next


The J2 Mean propagator is a first-order propagator that accounts only for the Earth's J2 geopotential model (Earth oblateness). No other effects, such as the Sun, Moon, or atmospheric drag, are modeled. The J2Mean propagator only takes Right Ascension of the Ascending Node and Argument of Perigee rates into account. A comparison between a J2Mean propagation and a numeric integration using, for example, an RK89, depends largely on whether the initial integration state is close to the mean orbit.
