Abstract EN
This paper introduces a new set of orbits, the “Repeated Shadow Track Orbits.” In these orbits, the shadow of a spacecraft on the Earth visits the same locations periodically every desired number of days.
The J2 perturbation is utilized to synchronize the spacecraft shadow motion with both the Earth rotational motion and the Earth-Sun vector rotation.
Motivation for the design of new shadow track orbits comes from the need to save energy.
The general mathematical model to design a Repeated Shadow Track Orbit (RSTO) is presented within this paper.
RSTOs' conditions are formulated and numerically solved.
Results show the feasibility of RSTOs.
An optimization process is also developed to maximize the shadow duration over a given site.
A Genetic Algorithm (GA) technique is utilized for optimization.
