                         filter to estimate the position and velocity of a spacecraft in an 
                         aerobraking maneuver around the Earth. The cis-lunar aerobraking 
                         of the Hiten spacecraft as well as an aerobraking in a LEO orbit 
                         are simulated in this paper. The simulator developed considers a 
                         reference trajectory and a trajectory perturbed by external 
                         disturbances combined with nonidealities of sensors and actuators. 
                         It is able to operate in closed loop controlling the trajectory at 
                         each instant of time using a PID controller and propulsive jets. A 
                         Kalman filter utilizes the sensor data to estimate the state of 
                         the spacecraft. The estimation algorithms and propagation 
                         equations used in this process are presented. The U.S. Standard 
                         Atmosphere is adopted as the atmospheric model. The main results 
                         are compared with the case where the Kalman filter is not used. 
                         Therefore, it was possible to perform an analysis of the Kalman 
                         filter importance applied to an aerobraking maneuver.",
