             abstract = "The objective of this paper is to study the station keeping 
                         maneuvers that will have to be performed by the CBERS 
                         (China-Brazil Earth Resources Satellite) satellite. The CBERS is a 
                         remote sensing satellite that is under development by China and 
                         Brazil. This satellite is planned to stay in a polar frozen orbit 
                         and station keeping maneuvers will have to be performed to keep 
                         its orbital elements in a specified range. This paper is devoted 
                         to study the correction of the semi-major axis, eccentricity and 
                         argument of periapse, that are three of the Keplerian elements 
                         that will change due to the orbit perturbations. An algorithm 
                         capable of calculating the bi-impulsive transfer orbit with 
                         minimum AV between any two Keplerian and coplanar orbits is 
                         developed and used to calculate the maneuvers expected for the 
                         CBERS satellite. Several maneuvers are simulated, both to change 
                         the orbital elements individually or in groups. This algorithm is 
                         based on the minimum AV Lambert's problem shown in Prado, (1993) 
                         and Prado Broucke (1994). In the format that it is implemented 
                         here it is possible to include constraints in the region of the 
                         orbit that an impulse can be applied. The advantage of this 
                         approach is that there is no approximation or linearization 
                         involved, and, in consequence, the method derived can be used to 
                         transfers of any magnitude.",
