The main idea is to consider that a satellite is in an orbit around the Earth and that it has its orbit is disturbed by one or more forces. Then, it is necessary to perform a small amplitude orbital correction to return the satellite to its original orbit, to keep it performing its mission. A low thrust propulsion is used to complete this task. It is important to search for solutions that minimize the fuel consumption to increase the lifetime of the satellite. To solve this problem a hybrid optimal control approach is used. The accuracy of the satisfaction of the constraints is considered, in order to try to decrease the fuel expenditure by taking advantage of this freedom. This type of problem presents numerical difficulties and it is necessary to adjust parameters, as well as details of the algorithm, to get convergence. In this versions of the algorithm that works well for planar maneuvers are usually not adequate for the out of plane orbital corrections. In order to illustrate the method, some numerical results are presented. %N Article ID 532708 %T Low-Thrust Out-of-Plane Orbital Station-Keeping Maneuvers for Satellites %@electronicmailaddress vivian.gomes@uol.com.br %@electronicmailaddress abertachini@terra.com.br %@secondarytype PRE PI %K Hybrid optimal control, Low thrust, Low-thrust propulsion, Numerical results, Orbital maneuvers, Out-of plane, Small amplitude, Station-keeping. %@usergroup administrator %@usergroup lattes %@usergroup secretaria.cpa@dir.inpe.br %@group DMC-ETE-INPE-MCTI-GOV-BR %@group DMC-ETE-INPE-MCTI-GOV-BR %@e-mailaddress vivian.gomes@uol.com.br %3 Gomes&Prado_2012.pdf %@secondarymark B5_ASTRONOMIA_/_FÍSICA B4_CIÊNCIA_DA_COMPUTAÇÃO B3_CIÊNCIAS_AGRÁRIAS_I B1_ENGENHARIAS_I B2_ENGENHARIAS_II B1_ENGENHARIAS_III A2_ENGENHARIAS_IV A2_INTERDISCIPLINAR B3_MATEMÁTICA_/_PROBABILIDADE_E_ESTATÍSTICA %F lattes: 6880903376164690 1 GomesPrad:2012:LoOuOr %@issn 1024-123X %@issn 1563-5147 %2 dpi.inpe.br/plutao/2012/06.21.18.26.15 %@affiliation Instituto Nacional de Pesquisas Espaciais (INPE) %@affiliation Instituto Nacional de Pesquisas Espaciais (INPE) %B Mathematical Problems in Engineering %@versiontype publisher %P 1-14 %4 dpi.inpe.br/plutao/2012/06.21.18.26 %@documentstage not transferred %D 2012 %V 2012 %@doi 10.1155/2012/532708 %A Gomes, Vivian Martins, %A Prado, Antonio Fernando Bertachini de Almeida, %@dissemination PORTALCAPES %@area ETES
