             abstract = "The trajectory of a spacecraft going to the periapsis of its orbit 
                         around the smaller body of a binary system is estimated from the 
                         observed data using a Kalman Filter. Simulations of the 
                         trajectories will be made to generate the data of the spacecraft 
                         position. When observed from the Earth, using a fixed star as a 
                         reference, we have the spacecraft position as an angle function 
                         \ϕ. This is the angle between spacecraft position vector and 
                         the star position vector. The result shows that Kalman Filter can 
                         be used successfully for trajectory estimation, if adequate 
                         accuracy is available for the angle observations.",
