Outline of Final Research Achievements |
The aim of this study is to systematize a variety of analyzing and processing methods for acquiring valuable information and knowledge for operators from a vast amount of telemetry data trasmitted from artificial satellites. For this purpose, we divided the whole study into four subtopics and conducted them - (1) data accessing methods, (2) online monitoring methods, (3) offline analyzing methods, and (4) methods for integration with other information sources. As a result, we obtained mainly four achievements - (1) clarification of characteristics of satellite telemetry, (2) development of preprocessing methods for telemetry data, (3) development and enhancement of health monitoring method based on dimensionality reduction and clustering, and (4) demonstration of the methods in the actual spacecraft operation.
