What is it about?

The periodic orbits of deputy satellite are analyzed when the chief satellite is moving in an elliptical orbit. &is analysis is developed on 1- to 10-loop periodic orbits of the deputy satellite. &ese orbits along with their associated loops are discussed under some specific initial position sets. &e effects of different initial velocities, initial true anomalies, and eccentricities on the initial position and orbital period of periodic orbits of deputy satellite are investigated.

Why is it important?

The formation flying of small multiple satellites as a replacement of using single large satellite has shown great interest for different defense- and science-based space missions. Formation flying consists of a set of satellites, which have the same dynamic state and governed by one control law. Abundance and precision of the proposed system in terms of formation satellites are more effective tools, which give a job more accuracy than using a conventional large single satellite.


Writing this article was a great pleasure as it has serious co-authors. This article also lead to Astrodynamics groups contacting me and ultimately to a greater involvement in Periodic Orbits within the Frame of Formation Satellites.
