Universidad de Zaragoza (orcid)0000-0002-3312-5710 Approximate trigonometric series expansions of some bounded solutions in the Tsien problem 2019 Access copy available to the general public Unrestricted INTHE last decades, studies on the dynamics of a spacecraft that is moving in the gravitational field of a celestial body and subjected to some low-thrust propulsion system have attracted the attention of many researchers in astrodynamics. Here, we consider a particular case, the so-called Tsien problem [1], in which the spacecraft moves in a circular Keplerian orbit (often referred to as the parking orbit), and after a given time t0 0, it is subjected to a constant outward radial acceleration. By using the integrals of energy and angular momentum, this problem can be reduced to a two-dimensional scenario. Denoting by r and ? the polar coordinates that give the position of the spacecraft in the plane of the orbit [1], the differential equations that define their motion are ... info:eu-repo/grantAgreement/ES/DGA-FEDER/E41-17R info:eu-repo/grantAgreement/ES/DGA-FSE/E24-17R info:eu-repo/grantAgreement/ES/MINECO/ESP2017-87113-R info:eu-repo/grantAgreement/ES/MINECO/MTM2016-77735-C3-1-P info:eu-repo/semantics/openAccess All rights reserved http://www.europeana.eu/rights/rr-f/ 2.692 2019 ENGINEERING, AEROSPACE 6 / 31 = 0.194 2019 Q1 T1 INSTRUMENTS & INSTRUMENTATION 21 / 64 = 0.328 2019 Q2 T1 1.573 2019 Aerospace Engineering 2019 Q1 Applied Mathematics 2019 Q1 Space and Planetary Science 2019 Q1 Electrical and Electronic Engineering 2019 Q1 Control and Systems Engineering 2019 Q1 info:eu-repo/semantics/article info:eu-repo/semantics/acceptedVersion Montijano, J.I.
