  Thesis title: "Spacecraft performance analysis and fault diagnosis using telemetry-mining".Abstract:In this thesis, artificial intelligent techniques are used to analyze the performance of satellite and its subsystems and diagnose operational faults. The case study and source of telemetry data are acquired from Egyptsat-1 satellite which has been launched in April 2007 and lost communication with ground station late in 2010.The performance analysis of this systems has been carried… Show more Thesis title: "Spacecraft performance analysis and fault diagnosis using telemetry-mining".Abstract:In this thesis, artificial intelligent techniques are used to analyze the performance of satellite and its subsystems and diagnose operational faults. The case study and source of telemetry data are acquired from Egyptsat-1 satellite which has been launched in April 2007 and lost communication with ground station late in 2010.The performance analysis of this systems has been carried out using different machine learning techniques: autoregressive integrated moving average, multilayer perceptron, recurrent neural network-RNN, long-short term memory RNN-LSTM, gated recurrent unit GRU, deep learning LSTM, deep learning GRU. Machine learning techniques have been applied to identify operating modes and corresponding telemetry parameters, and then logical analysis of data has been used in conjunction with fault tree analysis to determine the most probable reason of failure in satellites.
