Download or read book Semi Analytic Approach to Rapid Orbit Determination for the Perturbed Two Body Problem written by Erin Cope and published by . This book was released on 2023 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: Ensuring a safe operating environment for existing and future space objects relies on maintaining a catalog of existing resident space objects. As the number of space objects increases, it is imperative to improve the accuracy and computational efficiency of algorithms tasked to update the catalog periodically. Traditionally, this update has been done by processing measurements of the space objects using optical or radar sensors and incorporating simplified dynamical models to perform orbit determination. While optical sensors routinely provide angles-only data, traditional algorithms for orbit determination depend on methods that approximate the nonlinear dynamics of resident space objects. The goal of this thesis is to develop tools to incorporate information from the nonlinear dynamics while keeping the implementation of these orbit determination methods computationally tractable. Specifically, this thesis proposes to combine advancements in semi-analytic satellite theory with statistical methods to accurately compute a direct mapping between the NORAD elements and the state space in a derivative-free manner. This mapping is obtained using a set of orthogonal basis functions to create a polynomial model of the dynamics that relates a space object's state vector, as taken from the object's most recent catalog data (NORAD elements), to the object's position at the epoch of the measurement. The coefficients of these polynomials are found through the application of a non-product quadrature rule known as the conjugate unscented transform. The result is a larger domain of validity as compared to traditional methods of numerically propagating state transition matrices. This mapping is then incorporated directly within a non-linear least squares regression routine for orbit determination. The results of this regression are validated across various orbit regimes for multiple measurement models.

Download or read book Satellite Orbits Estimation Determination and Control written by Mohamed Zayan and published by LAP Lambert Academic Publishing. This book was released on 2010-10 with total page 236 pages. Available in PDF, EPUB and Kindle. Book excerpt: This thesis analyzes and develops the methods of accurate satellite orbits determination and estimation using adaptive Least Mean Squares (LMS), Kalman digital filters, and Adaptive Neural Networks (ANN). In addition, the thesis develops and implements satellite orbits controllers using an Adaptive Neural Network Predictive Control (ANNPC) technique. After a spacecraft has been placed in an operational orbit about the Earth, it will lose its orbit due to physical perturbation forces from the Earth, the Sun, and the Moon. Subsequent thrusting maneuvers will be required to correct the satellite orbit. Orbit estimation and determination are required with high accuracy, which are the first and the most important phase in preparation of the satellite-control-maneuver. The thesis specifically addresses the algorithmic implementation of the LMS and Kalman filters for the spacecraft orbit determination and estimation problem. The inherent advantages, disadvantages and trade-off, which are required to select the suitable method, have been analyzed. The orbit determination and estimation has been refined using multi-layers ANN with a non-linear function.
