Follower satellite
WebThis study mainly considers short-range flight-following missions in near-circular orbits, and the considered flight formation is defined as follows: (i) both the target satellite S T and follower satellite S F in the flight formation are in near-circular orbits such that the eccentricity of the two satellites is much less than 1; (ii) the follower satellite S F follows … WebThe follower satellite in the formation works without relative sensors, and its target pointing commands are derived based on relative orbital dynamics. The centralized estimator based on truth measurement is designed, however, this estimator is proved unstable because of the lack of necessary measurement information. After that, an alternative ...

WebOct 1, 2024 · As a new approach, target and follower satellite state estimations are obtained with the extended Kalman filter (EKF) using the Kepler orbit model. In contrast, these obtained state vectors are used for the relative motion estimations between the satellites which are created with the Hill-Clohessy-Wiltshire (HCW) relative model. WebJun 1, 2024 · The follower satellite's mass, the moment of inertia, and the moment arm of the thrusters are set to m = 200 kg, J z = 60 kg m 2, and (β 1, β 2) = (0.5, − 0.5) m, respectively, and the initial follower attitude is assumed to coincide with a desired angle with no angular velocity.
WebThe earth has its own rotation too, therefore the orbit of the satellite and the earth's rotation combinedly make the satellites orbit the entire earth. Without the earth's rotation, the satellite would just keep on following a … WebDownload Followers Tracker Lite and enjoy it on your iPhone, iPad, and iPod touch.
